That tune, "Glass Tambourine,'' clearly began with Timony. The songs on which she sang lead showed her taste for madrigal-style melodies and the courtly side of British prog-rock; they also featured bouncy backup vocals (provided mostly by keyboardist Rebecca Cole, but sometimes by drummer Janet Weiss) that recalled late-'60s psychedelic pop. Brownstein's influences tended more toward the '70s, suggesting the heavier rock style she brought to Sleater Kinney's last album, "The Woods.'' Indeed, some of Brownstein's high-pitched vocal flourishes seemed to be calling for a response from Corin Tucker, her musical foil in that band.
