For more than 20 years, the Japanese psychedelic rock band Acid Mothers Temple & the Melting Paraiso UFO have been creating some truly mind-expanding music on both the stage and studio. Their sound draws heavily on late ’60s/early ’70s brain-dissolving acts like Guru Guru, Gong, Faust, Amon Düül II and various other fellow prog/psych groups. Acid Mothers Temple’s music has been described as “extreme trip music,” an appropriate appellation for a group that’s a globally renowned collective sustaining the heavy psych music tradition of taking listeners on an intense journey to the outer realms of contemporary sounds.
