"Grunen" (The Greening) is a live totally improvised recording from the trio of pianist Achim Kaufmann, bassist Robert Landfermann, and drummer Christian Lillinger.

The Ember quartet's 2nd release recorded during the 2008 Ahornfelder Festival in Leipzig, an amazing live/studio album of distinct and clearly separated structured improvisations.

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.
