Once again, I seem to have missed the memo. Which is to say, I hadn't heard of these kids until last Saturday. (And which also means I actually have something to thank World's Most Irksome Rock Critic™ Jon Caramanica for, although I won't bore your with the details).
From All-Music Guide:
Yeastie Girlz (their name obviously a take-off on the Beastie Boys) were a short-lived feminist rap trio comprised of members Jane, Cammie, and Kate, hailing from the fertile punk scene of Gilman St. in Berkeley, San Francisco. The trio released a lone 7" EP in 1988, Ovary Action (issued on the independent Lookout! label), which contained a total of ten songs (only one of which stretches past the two-minute mark); some sample titles being "Sperm Brain," "Talkin' Shit," "Orgasm Addict," and "Fuck Yerself." Besides their single, not much else was heard from Yeastie Girlz.
Actually, my favorite is their "Sue Your Friends."
But in any case...
...I think I'm in lurve.
