Number19 was a band from Brooklyn, New York. It was formed in 1999 by Sarth Calhoun (bass, Yamaha EX5), Leah Coloff (voice, cello), Tony Diodore (guitar, violin), and Marcus Righter (drums). The band experimented with electronic sounds in alternative and indie rock settings, focusing on cello and violin swooping over grooving bass and drums. The band notably funded its first album, Suspension, from mp3.com downloads.
