Dub Spencer & Trance Hill have been in the music business for about 20 years and are still as hungry as a caterpillar in forest full of leaves. Together with their longtime companion Umberto Echo they present their new album «Imago Cells» live in Surround. Imago cells are responsible for a caterpillar's ability to transform into a butterfly. This served as the starting point for the new record: something old is overcome so that something new and more beautiful can emerge. Now it's not that Dub Spencer & Trance Hill wanted to overcome their dub roots. But it is in the nature of the four Musicians from Lucerne to climb unknown branches. The tracks sound much more electronic, Umberto Echo's dubmix skills, already legendary in stereo, reach a spectacular new level; what remains is the ecstatic live performance. So all fans of danceable dub, trance and organic techno music can expect an extraordinary sound experience that should not be missed.

Severin Prothmann, who today spins under the name Le 7è ciel, was a resident at the "Club Aera" (Zurich) as well as at the "Different Bar" (Bern) from 1991 on. His bookings led him from there over a multitude of locations in Lausanne, Neuchâtel, Lucerne, Basel, Bern and Zurich to Berlin. Since 1993 he produces electronic music under the label Zoul Guru Rec. and together with his wife Maria he is organizer and promoter of citytunes in Zurich since 2012.

He initially found his love for music through a classical education on clarinet, bass clarinet as well as saxophone and continued as a DJ from the age of 13. Initially, mainly funk, disco and jazz landed on Sevi's turntables before he was among the first in Switzerland to adopt hip hop. His commitment to this culture culminated in the opening of the legendary "Beat Bunker", Switzerland's first permanent rap club in Zurich North. His path as a DJ then led from rap to acid jazz to electronic music.
