Keith Jarrett - No End (2013)

Recorded at his home studio in 1986, the double album No End illuminates hitherto undocumented aspects of Keith Jarrett's music. He is heard on electric guitars, electric bass, drums and percussion, overdubbing tribal dances of his own devising: "Somehow something happened during these days in the 80s that won't ever be repeated," he writes in his liner notes. "There was really, to my knowledge, no forethought or composition - in the typical sense - going on; just a feeling or a rhythmic idea or a bass line concept or melody. None of this was written down."
