Is "Garage Beat '66" considered a standard yet? That series and "Back from the Grave" get the best stuff out.
"Psychedelic States" is hit or miss, and for whatever reason, whenever I find them in a shop, the discs are in really shit quality, even if they're still wrapped.
"Don't Press Your Luck: The In-Sound from Connecticut" and "We're Gonna Change the World!" are my two favorite regionals. I hate to sound like a Sundazed fanboy, but hell, I am. Oh well.
Oh! "Ft. Worth Teen Scene!" Classics, all!
