Ricochet is a live album by Tangerine Dream.
It was recorded on tour in England and France in 1975 and it’s said that it’s been pieced together from different concerts. That’s fairly common for tour based live albums but what makes it more unusual is that there are only two tracks.
Tangerine Dream were well known for their improvisations (like a jazz group) but with synthesizers.
