Billow Observatory

Billow Observatory is a trans-Atlantic ambient collaboration between Danish musician Jonas Munk (aka Manual) and Jason Kolb from the Michigan space rock band Auburn Lull. The two create vast, slow-moving vistas which occasionally tap into dubby textures. Their self-titled debut surfaced in 2012, and they've continued exploring their hypnotic, wintry sound on subsequent full-lengths and EPs including 2022's Stareside and 2025's The Glass Curtain.
