This is definitely an artifact of historical importance. It was one of the last shows ever performed at the Fillmore West as it was winding toward closure. It was also Roy Loney's final performance with The Flamin' Groovies. Both of those things make this well worth having for fans of the Groovies and those into this kind of music. These guys created a form of hard rock that's a bit rough around the edges and surely the kind of thing that would eventually give way to punk rock. There is a lot of jam band sound and psychedelia built into the mix, too. It should be noted that the recording quality here leaves a bit to be desired. There is a lot of channel drop out and distortion. Still, that's part of the experience.
