Define psychedelic. Caravan, with their Canterbury background, usually gets lumped in with early ‘prog’. Now, while you can endlessly debate what the tipping point between psych and prog might be, psych’s vital era was over with by early ‘68. Then there’s the front end, and ‘freakbeat’(which was more of a British thing). Which Kaleidoscope are you referring to? There was a French/UK band that owed a lot to Syd era Floyd, and then there was the US band that featured David Lindley...while they certainly emerged from psychedelia, they pioneered a type of world music fusion rock, but ultimately few people knew about them. Need more bands, and bass players, as examples. Currently, King Gizzard and Tame Impala get referenced a lot, but my fave is Temples, although they tend to lean toward the freakbeat side of things. For the record, I don’t consider The Dead as being all that ‘psych’ for very long; maybe through Aoxomoxoa, but then they became the proto jam band, and then proto-Americana with Workingman’s and American Beauty.
