"Tom Djll studied electronic music with Stephen Scott at the Colorado College, working with the EMS Synthi 100 system at Packard Hall. In 1978 and 79 Djll studied at the Creative Music Studio in Woodstock, NY, with Roscoe Mitchell, Anthony Braxton, Wadada Leo Smith, George Lewis, the Art Ensemble of Chicago, Karl Berger and many other giants of new music. He spent the years 1981-1993 working with the Serge Modular Music System before enrolling in Mills College Contemporary Music Program, where he extended his quest to develop and integrate an idiosyncratic trumpet language into an electronic sound environment, while also pursuing advanced improvisation studies, formally, with Pauline Oliveros, and, informally, with Jack Wright. While at Mills, Djll concentrated on microtonal composition, split-tone trumpet technique, and computer music. He also worked extensively with Chris Brown, resulting in contributions to Brown's recordings LAVA (Tzadik) and DUETS (Artifact).

Further refinement of trumpet languages and free improvisation with his band GROSSE ABFAHRT was undertaken from 1999 - 2010, published on the Emanem, Creative Sources, and Setola di Maiale labels. Beginning in 2012, Djll gradually re-introduced electronics into his sound-set. The results are heard in projects like hackMIDI (extreme electro-mechanical piano music), piano + analog electronics in TENDER BUTTONS (with Tania Chen and Gino Robair), delicate environments in EUPHOTIC (with Cheryl Leonard and Bryan Day), austere acoustic spaces with KOKUO (Kanoko Nishi-Smith, John McCowen, Jacob Felix Heule, and Kyle Bruckmann) and ongoing sessions and performances within the lively and ever-evolving Bay Area scene, including: Tim Perkis, Amanda Chaudhary, Jordan Glenn, Clarke Robinson, Suki O'Kane, Matt Ingalls, Tom Nunn, bran(...)pos, and Karen Stackpole.
