Gail Greenwood (born March 10, 1960) is an American musician notable for performing with the bands Belly and L7.
Having originally learned to play the baritone horn, Greenwood switched to guitar following high school. Her first band, the Dames, won the WBRU Rock Hunt in 1986. Later, Greenwood was a member of the Providence, Rhode Island-based band known as Boneyard, who opened for the Goo Goo Dolls and Social Distortion. In 1993, Throwing Muses alumna Tanya Donelly recruited Greenwood to join Belly as a bass guitarist. She played on that band's second album King and appeared on the cover of Rolling Stone. Donelly disbanded Belly in 1996 and Greenwood joined L7 as a bassist the following year. She continued with that group for three years. In 2001, Greenwood was recruited to play bass on tour in support of Canadian pop punk artist Bif Naked.
Greenwood and her partner, singer/bassist Chil Mott, continue to perform in Benny Sizzler, which formed in 2003. Other members of the band are guitarist Mark Tomis (formerly of Uber Alles, One Ton Shotgun, and The Motormags and currently in the diePods) and drummer Tom Berglund (who is currently in MEDS). Alumni of this band include the late guitarist/singer Gene Severens (who had played with Greenwood in Boneyard) and guitarist Terry Linehan (a fill-in guitarist for Green Day). Greenwood and Mott remain active in anti-sprawl efforts, promoting the retention of open spaces, responsible development and lobbying for land conservation in the face of tremendous pressure by big-box corporations including Wal-Mart.
