Since 2002 this large ensemble electric supergroup or "freakestra" has performed uncompromising free improvisation that draws on the best of modern approaches in a staggering display of style and technique.

The first album from 2006 of the Ember electro-acoustic improvising chamber jazz-oriented quartet of Urs Leimgruber on soprano & tenor saxophones, Alexander Schubert on guitar, electronics & percussion, Oliver Schwerdt on piano, percussion, guitar & electronics, and Christian Lillinger on drums & percussion; an album of insightful and meticulous interaction.
