Born from his uncommon versatility as award wining composer and performer (guitar/voice), Keller's music explores the myriad of possibilities in the coexistence, inter-mingling and hybridity between contemporary concert music, jazz and rock. Keller has received commissions from John Zorn (Tzadik), the Empyrean Ensemble (UC Davis), Fondation Royaumont, Redfish-BlueFish, NOISE, Colin McAllister (gutiar), JitaZax, City Water, Cantoria (Truman University), Cappella Gloriana, the Athen Master Chorale, Mark Menzies violin),
and Morris Palter (percussion). His music has been performed in the Americas, Europe, and Australia, and at notable festivals such as The World Saxophone Congress, June in Buffalo, SoundOn (La Jolla, CA), and the Festival of New American Music (CSUS).
In addition to being a composer, Keller is an accomplished guitarist. He has won and placed in numerous state, regional and national competitions and performed in notable master classes, such as those with Christopher Parkening. With his own ensemble, he has performed at music festivals, including the Festival of New American Music (2013, 12, 07), In The Flow (2006, 08, 11), and the 2007 SRING festival of New Music at the University of California, San Diego.
Of late Keller has been making regular use of his vocal talents. While completing his Ph.D. in Music Composition at UCSD, Keller studied voice with Carol Plantamura. While in San Diego, he was a member of Cappella Gloriana, with which he performed in Europe, and for which Keller composed extensively. Currently Keller is a member of Resurrexit and is the Tenor Choral Scholar at Trinity Episcopal Cathedral (Sacramento, CA). Some of Keller's recent performances include singing his own arrangements of Schubert, Dowland, and Gesualdo for guitar and voice with the McAllsiter Keller Duo, selections from Four Andalusian Love Songs for countertenor and piano by Sacramento area composer Kurt Erickson, and selections from Récitations for solo voice by George Aperghis.
Keller’s music and performances are available on the Tzadik and Centaur labels. He holds a Ph.D. in music composition from the University of California, San Diego (2004).
