Tom Djll spent the years 1981-93 working with the Serge Modular Music System before enrolling in the Mills College Contemporary Music Program. Those years were largely taken up with a quest to develop and integrate an extended trumpet language into a post-WDR electronic sound environment, while also pursuing advanced studies in improvisation and performance with Pauline Oliveros and Jack Wright. While at Mills, Djll concentrated on microtonal music, split-tone trumpet technique, and computer music. Further development of trumpet languages and ‘EAI’-style free improvisation with his band Grosse Abfahrt was undertaken from 1999 – 2010, after which period Djll gradually re-introduced electronics and traditional keyboard technique into his sound-set. The results are heard today in his projects such as hackMIDI (extreme mechanical piano music), the hardcore free-noise trio BEAUTY SCHOOL, and ongoing free improvisation in the lively and ever-evolving Bay Area scene, with playing partners old and new (including but not limited to Gino Robair, Julia Mazawa, Tim Perkis, Kyle Bruckmann, Jacob Felix Heule, Suki O’Kane, Matt Ingalls, Tom Nunn, bran(…)pos, and Karen Stackpole, as well as international players.
