As spring dawns, nostalgia fills the air. This week DJ Andy Bargerstock takes us back to the Underground music of the early 1970s. The music of Randy California and Spirit (photo) get top billing. You will hear rarely heard track "Cosmic Smile" and three tracks from the incredible LP Twelve Dreams of Dr. Sardonicus.

Then, sink deeply into the couch, turn down the lights, bring out the headphones to catch the full effects of these extremely rare tracks: "Church of Anthrax" by John Cale & Terry Riley, "Sleepwalker's Timeless Bridge" by Amon Duul 2, "The Mask" by Roger Glover, and "Wayfaring Pilgrim" by Roy Buchanan & the Snakestretchers. As the night unfolds, you will also hear fine tunes from Wishbone Ash, Savoy Brown, Fripp and Eno, Robin Trower, and It's a Beautiful Day. Oh, yes, let's not forget Quicksilver Messenger Service! What a perfect night to gain a better understanding of ourselves and the universe.
