In the early 1990s, Sorrentino, her brother Jay (drums), and high school friend Ken Heitmueller (bass) formed the music trio Suddenly, Tammy!.

The band was signed by spinART Records, which released two EPs (Spokesmodel, El Presidente), produced by Sean Slade, and a self-titled debut album.

Sorrentino recorded a series of demos between 2002 and 2003, produced by Irwin Chusid and engineered by Peter Katis at Tarquin Studios, in Bridgeport, Connecticut.

After sporadic returns to public performance in New York clubs, Sorrentino approved the demos for digital release in 2006 under the title Nine Songs, One Story.

During 2011 and 2012, Sorrentino provided keyboard accompaniment on an intermittent basis at the program's biweekly live broadcasts from the Upright Citizens Brigade Theatre on West 28th Street.
