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.
Jane Vain and the Dark Matter is an indie rock band formed in 2005 from Calgary, Alberta, Canada.
 The band is fronted by Calgary native Jamie Fooks, and signed to Edmonton’s Rectangle Records.
 They describe their sound as indie electro-pop.
 The "Montreal Mirror" called their music “melancholy" and "macabre,” and Fooks has been compared to Emily Haines, Cat Power, and Fiona Apple.
 They released their first full-length album, "Love Is Where the Smoke Is", in January 2008.
Emily Haines (born January 25, 1974) is a Canadian singer and songwriter.
 She is best known as the lead singer, keyboardist and songwriter of the rock band Metric and a member of Broken Social Scene.
 As a solo artist, she has performed under her own name and under the moniker Emily Haines & The Soft Skeleton.
 Haines possesses a soprano vocal range.
The Beast Is Back is the seventh album by a newly reformed Blue Cheer, 13 years after their previous album, "Oh!
 Pleasant Hope" (1971).
 It contains re-recorded versions of some of the band's most popular songs from their late-1960s heyday as well as new material.
 The album features founding members Dickie Peterson and Paul Whaley.
 Original guitarist Leigh Stephens did not participate in the reunion.
Paul Whaley (born January 14, 1946) is an American drummer best known as the drummer for rock band Blue Cheer.
 He was the son of country music singer Paul Whaley Sr.
 He grew up in the towns of Vallejo and Winters California.
 He played drums with a Davis, California band called the Oxford Circle.
 Whaley is credited on the Oxford Circle album "Live at the Avalon 1966".
 When he left the Oxford Circle to join Blue Cheer in 1967, the former band dissolved.
 He was the longest-standing member in Blue Cheer other than founder Dickie Peterson in the band when it broke up in late 2009, following Peterson's death at age 63.
What is Free to a Good Home?
 is the first extended play (EP) by Emily Haines & The Soft Skeleton.
 The EP consists of five new songs and a remix, including previously unreleased tracks from the sessions of "Knives Don't Have Your Back".
 It was released July 24, 2007 in Canada and the United States on Last Gang Records.
 The title of the EP comes from a poem by Emily Haines' father, Paul Haines.
Richard Allan Peterson (September 12, 1946 – October 12, 2009) was an American musician, best known as the bassist and lead singer for Blue Cheer.
 He also recorded two solo albums: "Child of the Darkness" and "Tramp".
Forgiveness Rock Record is the fourth studio album by Canadian indie rock musical collective Broken Social Scene, released by the Arts & Crafts record label on May 4, 2010.
 The critically acclaimed album, produced by John McEntire of the band Tortoise, features guest appearances by Leslie Feist, Emily Haines of Metric, Scott Kannberg from Pavement, and Sebastien Grainger of Death from Above 1979.
Oh!
 Pleasant Hope is the sixth, and last, album by Blue Cheer until 1983's "The Beast Is Back".
 It features less psychedelia and hard rock and includes more folk rock elements.
 This is an unusual Blue Cheer album in that Dickie Peterson only sings lead on three songs.
 Another unusual aspect is that the song "I'm the Light" features extensive use of the sitar and synthesizer, although on the previous album "The Original Human Being" the song "Babaji (Twilight Raga)" also featured extensive use of the aforementioned instruments.
Broken Social Scene is a Canadian indie rock band, a musical collective including as few as six and as many as nineteen members, formed by Kevin Drew and Brendan Canning.
 Most of its members play in various other groups and solo projects, mainly in the city of Toronto.
 These associated acts include Metric, Feist, Stars, Apostle of Hustle, Do Make Say Think, KC Accidental, Emily Haines & The Soft Skeleton, Amy Millan, and Jason Collett.
