Program Notes:

The relationship between music and visual art goes back further than film, musical theater, and opera. When composers render music in written form, the result can be a work of art in its own right, whether it is the florid manuscripts of medieval plainchant or the barely legible sketches of Beethoven. 

We recognize the modern multimedia synergy in our generation of Flash, the Internet, and MTV. Therefore, in tonight’s program, we pay tribute to George Crumb, known for his visually arresting musical scores, by accompanying the performance of his work with a real-time, digital visualization by Al Matthews. By using a sophisticated symbolic language centered on comic strips, Jennifer Walshe challenges the ensemble to create musical sounds related to a compelling visual score.  And Jason Freeman’s work invites the audience to manipulate a web-based visual representation of his score in order to shape future concert performances of the piece.

Technology has not only enabled composers to create new kinds of scores and take new approaches to multimedia, it has also enabled them to explore new worlds of sound. George Lewis incorporates elements of hip-hop and basketball in the computer-generated sounds that accompany a solo percussionist. George Crumb uses extended instrumental techniques, some of which are only audible with amplification, to imitate the sounds of humpback whales. And Daniel Lentz uses wine glasses and bursts of spoken phonemes to create a live multi-track studio on stage, gradually building up coherent musical textures and phrases over the course of the performance.


George Lewis’ North Star Boogaloo (1996), for percussion and computer, is a setting of a poem of the same name by Quincy Troupe.  It was written for percussionist Steven Schick, who explains the title in his book, The Percussionist’s Art: “…the North Star was the singular guiding light that led slaves to freedom as they escaped the plantations of the South and headed north. Basketball as a modern-day North Star beckons to many, especially to young African Americans, who have seen it as a beacon to the kind of freedom that comes from fame and affluence.” The percussion part is completely notated, and the computer program, written by George Lewis using Ron Kuivila and David Anderson's program FORMULA (FOrth MUsic LAnguage), plays samples, beats, and other percussion parts, and delivers the poem's text, using samples from the author's own voice. The computer's delivery of the poem's text serves as Lewis' loving kind of signifying on Quincy's powerful performance persona.

George Crumb writes: “Vox Balaenae (Voice of the Whale), composed in 1971 for the New York Camerata, is scored for flute, cello and piano (all amplified in concert performance).  The work was inspired by the singing of the humpback whale, a tape recording of which I had heard two or three years previously.  The form of the work is a simple three-part design, consisting of a prologue, a set of variations named after the geological eras, and an epilogue.  The opening Vocalise is a kind of cadenza for the flutist, who simultaneously plays her instrument and sings into it.  The conclusion of the cadenza is announced by a parody of the opening measures of Strauss’ Also sprach Zarathustra.  The Sea-Theme is presented by the cello (in harmonics), accompanied by dark, fateful chords of strummed piano strings.  The following sequence of variations begins with the haunting sea-gull cries of the Archezoic and, gradually increasing in intensity, reaches a strident climax in the Cenozoic. The emergence of man in the Cenozoic era is symbolized by a partial restatement of Zarathustra reference.  The concluding Sea-Nocturne is an elaboration of the Sea-Theme.  In composing the Sea-Nocturne I wanted to suggest “a larger rhythm of nature” and a sense of suspension in time.  The concluding gesture of the work is a gradually dying series of repetitions of a 10-note figure.” Tonight’s performance is complemented by a real-time video, created by Al Matthews, which applies visual effects to live and pre-recorded video based on a dynamic audio analysis of the performance. We hope it enhances and guides your listening of the music.

Daniel Lentz’s "You can't see the Forest…Music" (1971) is scored for "three speaker-drinkers with three wine glasses (with mallets) and red wine." The performers tap occasionally on the glasses, taking sips of the wine from time to time, so that the tapping pitch rises microtonally throughout. Meanwhile, they intone seemingly random phonemes (nt, ee, est, rr, etc.). All of this is recorded and played back as it is performed. As a result, a gradual microtonal cluster builds from the tapped wine glasses, while the spoken phonemes slowly coalesce into familiar aphorisms, such as the one suggested in the title.  The piece concludes with the performers slowly draining the glass, while the recording shimmers into a sparkling cluster accompanying comically mundane adages (“you can lead a horse to water…”).

It may seem odd for a solo violin piece to be performed on a concert dedicated to music and technology, but that is part of the point. Just as technology has made it possible to electronically generate and manipulate sounds, to create intelligent machine musicians, and to perform with novel musical interfaces, it has also enabled composers to transform the ways in which they approach the process of creation, interact with performers and audiences, and disseminate their work. Graph Theory (2006) seeks to connect composition, listening, and concert performance by coupling an acoustic work for solo violin to an interactive web site. On the web site, users navigate among sixty-one short, looping musical fragments to create their own unique path through the composition. The navigation choices which users make affect future concert performances of the work. Before each performance, the soloist prints out a copy of the score from the web site. That score presents her with a fixed path through the piece; the order of the fragments is influenced by the decisions that recent web site visitors have made. Graph Theory, a 2005 commission of New Radio and Performing Arts for its Turbulence web site, was created in collaboration with designer Patricia Reed and violinist Maja Cerar. It was made possible with funding from the Greenwall Foundation. It is available at http://turbulence.org/Works/graphtheory and on a kiosk in the lobby.

In Jennifer Walshe’s “meanwhile, back at the ranch…” (2005), for any number of performers and an image controller, the image controller draws and manipulates images projected onto a screen by a video camera.  The performers watch the images, which the image controller annotates on the screen.  The image controller breaks down the images, designating different elements for each performer.  The performers then improvise sounds to represent the images they are assigned according to a sophisticated visual notation system described in the composer’s instructions.

About the Musicians:

George Crumb's reputation as a composer of hauntingly beautiful scores has made him one of the most frequently performed composers in today's musical world.  Crumb was born in Charleston, West Virginia in 1929.  He has received degrees from Mason College of Music, the University of Illinois, Champaign-Urbana, and the University of Michigan, Ann Arbor. Crumb's music often juxtaposes contrasting musical styles. The references range from music of the western art-music tradition, to hymns and folk music, to non-Western musics. Many of Crumb's works include programmatic, symbolic, mystical and theatrical elements, which are often reflected in his beautiful and meticulously notated scores.  George Crumb is the recipient of numerous awards including the Pulitzer (1968), a Grammy (2001), Musical America’s “Composer of the Year” (2004), and the Prince Pierre de Monaco Gold Medal, grants from the Guggenheim, Rockefeller, and Fromm foundations, and 6 honorary degrees. He is a member of the National Institute of Arts and Letters as well as the Deutsche Akademie der Kunste.

Jason Freeman’s works break down conventional barriers between composers, performers, and listeners, using cutting-edge technology and unconventional notation to turn audiences and musicians into compositional collaborators. His music has been performed by the American Composers Orchestra, Speculum Musicae, the So Percussion Group, the Nieuw Ensemble, Le Nouvel Ensemble Moderne, and Evan Ziporyn; and his interactive installations and software art have been exhibited at the Lincoln Center Festival, the Boston CyberArt Festival, and the Transmediale Festival and featured in the New York Times and on National Public Radio. N.A.G. (Network Auralization for Gnutella) (2003), a commission from Turbulence.org, was described by Billboard as “…an example of the web’s mind-expanding possibilities.” Freeman received his B.A. in music from Yale University and his M.A. and D.M.A. in composition from Columbia University. He is currently an assistant professor in the music department at Georgia Tech.
