Martin Stürtzer shares a three-hour improvised ambient birthday session

German composer Martin Stürtzer has shared a three-hour live ambient improvisation, according to Synthtopia. It is his "three hours long birthday session", a spontaneous idea from eight years ago that has become a yearly tradition. Stürtzer says he spent the preceding weeks preparing sound patches and sequences on his synthesizers, and that the set is mostly improvised.

Stürtzer works in dark ambient. His newest studio album, according to MusicBrainz, is “Invisible Places”, released on 16 October 2026.
