There were two classic bands active in the late sixties. There was a band from California named Kaleidoscope which was essentially in more of a folk psychedelic vein. They recorded four albums between 1966 and 1970. I'm familiar with the first two. Anyhow check this out.
Then there was a band known as Kaleidoscope from the UK from around the same period. They too were psychedelic but they of more of a paisley pop vein. At times they could get a little spacey. They recorded only two albums. This is my favorite song from them.
So which one's better? I would have started a poll but I didn't want to have to include the Starland Vocal Band
