Berlin-based Suns of Thyme formed in 2011, crafting a strain of heavy psychedelia that merges stoner rock, shoegaze, krautrock, and post-rock influences evoking Can, early Pink Floyd, and Spacemen 3. The quartet released their debut Fortune, Shelter, Love and Cure before the five-piece follow-up Cascades in 2016, which expanded into space rock and death rock territory. They have been featured alongside Brian Jonestown Massacre and Kadavar on German compilations and supported UK shoegazers TOY.
