This bootleg offers both sets recorded at Max's Kansas City by Brigid Polk on August 23, 1970. Unfortunately last song from second set (Lonesome Cowboy Bill) is missing. Sound quality is close to the official Live at Max's release and anyway superior to many previous bootleg releases of the Max's stuff.
this is from the silver set of Flowers of Evil. It's just the Max's stuff, as the other tracks can be found, more complete, somewhere else.
