Before her days in Sleater-Kinney, Corin Tucker was belting out screams with her riot grrrl duo, Heavens to Betsy. Along with drummer and bassist Tracy Sawyer, Tucker crafted 12 songs of pissed-off, bitter confusion. The song "White Girl," is a rare introspective look by someone in the indie scene addressing the audience directly about the topic of racism. Intensely fierce, even when the tempo slows down, Sawyer keeps the beats tight and Tucker is always brimming over with passion and the kind of power of which many bands in the hardcore scene aren't even capable. Calculated should be included as essential listening for all fans of riot grrrl.
