Tanya Donelly (born July 14, 1966, in Newport, Rhode Island) is an American Grammy Award-nominated singer-songwriter and guitarist based in New England who co-founded Throwing Muses with her stepsister Kristin Hersh.
 She then went on to work in The Breeders and Belly in the 1990s.
 In the late 1990s, she settled into a solo recording career, working largely with musicians connected to the Boston music scene.
The discography of American alternative rock band The Breeders consists of four studio albums, one live album, three extended plays, ten singles and twelve music videos. Kim Deal, then-bassist of American alternative rock band the Pixies, formed The Breeders as a side-project with Tanya Donelly, guitarist of American alternative rock band Throwing Muses.
 After recording a demo tape, The Breeders signed to the English independent record label 4AD in 1989.
 Their debut studio album "Pod" was released in May 1990, but was not commercially successful.
 After the revival of the Pixies and Throwing Muses in 1990, The Breeders became mostly inactive until the Pixies' breakup in 1993.
 With a new lineup, The Breeders released their "Safari" EP in 1992, followed by their second studio album "Last Splash" in 1993.
 "Last Splash" was The Breeders' most successful album; it peaked at number 33 on the United States "Billboard" 200 and was certified platinum by the Recording Industry Association of America in 1994.

Throwing Muses is an alternative rock band formed in 1981 in Newport, Rhode Island, that toured and recorded extensively until 1997, when its members began concentrating more on other projects.
 The group was originally fronted by two lead singers, Kristin Hersh, and Tanya Donelly, who both wrote the group's songs.
 Throwing Muses are known for performing music with shifting tempos, creative chord progressions, unorthodox song structures, and surreal lyrics.
 The group was set apart from other contemporary acts by Hersh's stark, candid writing style; Donelly's pop stylings and vocal harmonies; and David Narcizo's unusual drumming techniques eschewing use of cymbals.
 Hersh's hallucinatory, febrile songs occasionally touched on the subject of mental illness, more often drawing portraits of characters from daily life or addressing relationships.
Belly is an alternative rock band formed in Boston, Massachusetts in 1991 by former Throwing Muses member Tanya Donelly (who was also in The Breeders).
 The original lineup consisted of Donelly on lead vocals and guitar, Fred Abong on bass, and brothers Tom and Chris Gorman on guitar and drums respectively.
 Although formed in Boston, the group's members are all from the Newport, Rhode Island area, and identify themselves as a Rhode Island band as opposed to a Boston one.
