That was Marnie Greenholtz.
Thalia was the singer on the last few records... 87 on?
My cousin was a friend of theirs and was way into them...I liked Live Skull's records well enough but thought they were sort of a dour sub-SY also-ran. I never saw them though.
That one album cover of theirs with the lobster with a knife in it is pretty hard. Bought that one for the sleeve for sure.
