Wow, I've never heard of that band and from the looks of the cover I would say the vintage is late '60s to early '70s. I was in a haze during that time but thought I listened to almost everything during the period.
See you at the Rave wink wink. I only have one lp by them, they did 3 total. I have all 3 on CD
I think I might have the other 2 on reissue vinyl.

but I'm not sure. The originals are pricey
