Switzerland native Thomas Fehlmann’s history in Berlin’s electronic music scene runs deep: Since 1984, he has been active as a producer, label head, radio host, and club DJ at legendary spots like Tresor. With Böser Herbst (“Bad Autumn”), he casts a glance back in history, to 1929. The album was produced as the soundtrack for the third season of Babylon Berlin, a noir drama set at the peak of Weimar Germany, and Fehlmann’s music is appropriately atmospheric: Synths swirl in a foggy haze, minimalist beats clack like footsteps on cobblestones. The dub effects so common to his work, both solo and as a member of The Orb, are all but non-existent; in their place, he avails himself of the expressive possibilities of the loop, cycling through short, filtered phrases of piano and strings, and stretching them out toward infinity. The mood is muted, wavering somewhere between melancholy and paranoia. Kompakt fans may be reminded of Wolfgang Voigt’s beloved Gas project: As on albums like Pop and Königsforst, Fehlmann’s mix of 4/4 beats and electro-acoustic treatments yields an unsettling look back at German history.
