Martin Stürtzer

Martin Stürtzer is an Ambient / Electronic / Dub Techno artist from Wuppertal (Germany). I work with analog, digital, hardware and virtual instruments to create Ambient, Electronic and Dub Techno music. I release music on CD / Vinyl / Bandcamp and play live. In march 2020 I started the Home Concert series where I play a live show from my studio on every first sunday of the month at 20:00 CET. I am also running the dark ambient projects Phelios & Sphäre Sechs and organise a dark ambient festival in a church called Phobos Festival.
