Metric is a Canadian rock band founded in 1998 in Toronto. The band consists of Emily Haines (lead vocals, synthesizers, guitar, tambourine, harmonica, piano), James Shaw (guitar, synthesizers, theremin, backing vocals), Joshua Winstead (bass, synthesizers, backing vocals) and Joules Scott-Key (drums, percussion). Although the band is Canadian, Haines was born in India and Winstead is American. The band started in 1998 as a duo formed by Haines and Shaw with the name "Mainstream". After releasing an EP titled Mainstream EP, they changed the band's name to Metric, after a sound that was programmed by Shaw on his keyboard. In 2001, Winstead and Scott-Key joined them.
