L7 Bricks Are Heavy 1992

Wikipedia:

L7 was formed by Donita Sparks and Suzi Gardner on shared electric guitar and shared vocals. A year previous, Gardner had performed backing vocals on the Black Flag song "Slip It In". The punk rock duo were soon joined by Jennifer Finch on bass guitar and Roy Koutsky on drums. Koutsky left shortly after and Demetra Plakas ("Dee" for short) became their permanent drummer.

The band's name derives from a 1950s slang phrase meaning "square," but is often mistaken for a reference to the sex position, "69".
