This week we concentrate (for the most part) on the core years of the psychedelic era, 1966-68. We don't start there, however. Instead we do a reverse progression (a regression?) from 1969 on back to 1966, finishing out the segment with a quartet of B sides. The next half hour is made up entirely of tracks from 1967, including a rarely heard Dave Van Ronk classic. The second hour returns to 1966 for a set and then goes off on a tangent with early examples of progressive rock and Japanese heavy metal (!), before returning to the psychedelic era and a closing set from 1968.
