Causa Sui is a Danish instrumental psych-rock / stoner rock band composed of Jakob Sktt, Jonas Munk, Rasmus Rasmussen and Jess Kahr. Beginning with their eponymous debut album, the band has released fourteen albums since 2005. Causa Sui’s heavy sound is supplemented by abstract, instrumental and ambient styles akin to electric Miles Davis, or Can, particularly on their ‘Sessions’ series of albums, which feature guest musicians. Other cited influences include Popul Vuh, The Allman Brothers Band, Gabor Szabo, and Tame Impala.

Originally the Summer Sessions were intended as a side project for the band a chance to explore their love for other genres such as American free jazz, krautrock, 1970s soundtracks, as well as the psychedelia and detuned stoner-rock that characterized Causa Suis first two albums. But these three albums came to define the band, and have become become modern classics of psychedelia and progressive rock since their were initially released ten years ago. In a scene often characterized by loyalty to a specific period, theres something refreshing about Causa Suis eclectic approach.
