They Might Be Giants (often abbreviated as TMBG) is an American alternative rock band formed in 1982 by John Flansburgh and John Linnell. During TMBG's early years Flansburgh and Linnell frequently performed as a duo, often accompanied by a drum machine. In the early 1990s, TMBG expanded to include a backing band. The duo's current backing band consists of Marty Beller, Dan Miller, and Danny Weinkauf. The group is best known for an unconventional and experimental style of alternative music. Over their career, they have found success on the modern rock and CMJ charts. More recently they have also found success in children's music, and in theme music for several television programs and films.
