Through the depths of the Colorado music comes Myelin ranging ages from 16-19. Formed in June 2006 they have searched for a guitarist but have been unsuccessful. They just released a 3 song demo in which they will be recording a full length this summer.

Myelin is the duo of Birgit Ulher (trumpet, radio, mutes, speaker, objects) and Heddy Boubaker (alto saxophone, objects). Their first release as a duo (as simply Birgit Ulher & Heddy Boubaker) was 'Upside Down' (2008 Herbal International, in their Why Not Ltd. series). Then they chose the monicker Myelin and proceeded to release a second duo album in December 2011 ('Axon', on Russian label Intonema). It was one of the last recordings on which Boubaker can be heard playing the saxophone; in the meantime he has switched to electric bass and analog modular synth. Read more on Last.fm.
