Electro-acoustic music

  • Hofmann (2018) ‘Tight-Interlocked Oscillators’ appears on CD compilation “Drop The Beat” EDITION DEGEM ‎– ed07.

The piece has also been presented in the Acoustic Frontiers radio show on Monday March 4th, 2019 presented by Ralph Hopper on CKCU FM 93.1.

EM-Doku holds an overview of a couple of my contemporary pieces, especially those that are in the archive of the TU-Berlin or Hmtm-Hannover: ‘Verbraufte Kusik’ (2010), ‘Isolation im Kollektiv’ (2007), ‘Burn Out’/’Me against Myself’ (2006-2010)

Solo-Performances

  • June 2018: Solo Performance @ LAC2018 (Artisana, Berlin, DE)
  • Sept. 2015: Invited solo-concert at Kontakte Festival ’15 (Akademie der Künste Berlin, DE)

In 2018 the COSMO (Csound On Stage Musical Operator) Project ported Csound to the Bela/Beagle Bone board. This opens up totally new live-electronics possibilties with the saxophone. For my latest performance, I build a device with a speaker and a microphone + Bela + COSMO which fits inside the acoustic instrument. This gives me a lot of freedom to move around during the performance and creates a good mix of electronic and acoustic sound. Here are some pictures from my current setup:

COSMO-Collective

COSMO Collective is an open musical collaboration for musicians using DIY electronics and custom software written in Csound. There is no definite musical style, though it could perhaps be characterized as electro-acoustic improvisation. The focus is on the exploration of sound and timbre, rather than traditional harmonics and rhythm, and exploiting the powers of Csound in this pursuit.

The core of the group are the original members Alex Hofmann (saxophone and electronics) and Bernt Isak Wærstad (guitar and electronics), but a performance can consist of any number of players. COSMO Collective have performed several shows around the world, including New York, St. Petersburg, Boston, Berlin and Trondheim.
