Soft Machine, I was quick to realize there was a lot more where they came from. Seems the town of Canterbury was responsible for turning out a lot of talented bands with a lot of new and interesting ideas about music.
One of those bands was Caravan - a really interesting mixture of rock, jazz, fusion and noise, all in one big overwhelming dose. Like Soft Machine, they weren't a band you could dance to - nor would you really want to. They came along at a time bands stopped being listened at and started being listened to. It was the start of what came to be known as Prog-Rock. Not for everybody. In fact Prog-rock really never took off in the States. By the early 70's the audience was fitting in with the whole Eagles-Linda Ronstadt-Black Oak Arkansas thing. Which was fine, but some of us wanted more to chew on.
Bands like Caravan did just that.
This is off their 2nd album released in 1970 "If I Could Do I All Over Again I'd Do It All Over You" - the title track, no less.
