In 1991, Susanna issued a pop-heavy solo album, When You're a Boy. Five years later, her eponymous LP brought her closer to her musical roots than she'd been in a long time which was met with critical praise. After working together in the Austin Powers films, Susanna and Matthew Sweet formed Sid 'n Susie, releasing three volumes of their acclaimed Under the Covers series. In 2011, she stole away to the studio for Someday, a retro modern solo set that served as a stylish homage to the '60s pop that she grew up on. She followed that up in short order with two EPs.
More recently, Susanna has collaborated with the Zombies, Tom Petty, Chris Martin, Mike Campbell, Jack Antonoff, Fred Armisen and Carrie Brownstein, Aimee Mann, Andrew Bird, Jon Brion, Maya Rudolph, and others.
