" Stoner Rock combines Blues Rock, the psychedelic elements from Psychedelic Rock, and the repetitive riffs of Doom Metal. Guitars are tuned low, the bass is heavy and tempo is mostly slow-to-mid. The vocals and production are usually raw.
The term stoner rock comes from the genre's connection with the use of marijuana, stoner being a slang term for a user of cannabis. It is sometimes believed that the bass heavy and psychedelic sound is meant to enhance the effects of drugs. The roots are in '60s and '70s bands like Black Sabbath and Blue Cheer, but what is called Stoner Rock today was pioneered by Californian bands such as Kyuss, Sleep and Fu Manchu. "
