The Saskatoon Symphony Orchestra (SSO) is a professional orchestra based in Saskatoon, Saskatchewan administered by the non-profit Saskatoon Symphony Society.
 The orchestra was founded in 1927 as an amateur orchestra, but today has 10 core members and up to 50 sessional musicians.
 Arthur Collingwood, who was Professor of Music at the University of Saskatchewan, presented the first SSO concert.
 The SSO received major funding from the Carnegie Institute in 1931.
 The Canada Council, the Saskatchewan Arts Board, and the City of Saskatoon have all provided sponsorship of the SSO through the years.
 In the spring, the symphony holds a Saskatoon Symphony Book & Music Sale to raise funds for the orchestra.
 The SSO itself offers students grants and hosted a national cello competition in 1990.
 Dwaine Nelson was responsible for the development of a full-time core of musicians, initially with a size of six, but later expanded to the present-day ten members.
 In the summer of 2014, the SSO announced that Maestro Victor Sawa would move into the position of Conductor Emeritus at the end of the 84th season.
 In March 2015, the SSO announced Eric Paetkau as the 16th Music Director of the orchestra.

The North Shore consists of many affluent suburbs north of Chicago, Illinois, bordering the shores of Lake Michigan.
 These communities fall within suburban Cook County and Lake County.
 The North Shore's membership is often a topic of debate, and is sometimes expanded to include other affluent Chicago suburbs which do not border Lake Michigan.
 However, Evanston, Wilmette, Kenilworth, Winnetka, Glencoe, Highland Park, Lake Forest, and Lake Bluff are generally considered to be the core members of the North Shore, as all are affluent communities that border the lake just north of Chicago.
 Other suburbs such as Glenview, Northbrook, Deerfield, Highwood, Skokie, and Northfield are often considered to be a part of the North Shore, but do not border Lake Michigan.
Acid Mothers Temple & the Melting Paraiso U.F.O. (and subsequent offshoots) is a Japanese psychedelic rock band, the core of which formed in 1995.
 The band is led by guitarist Kawabata Makoto and early in their career featured many musicians, but by 2004 the line-up had coalesced with only a few core members and frequent guest vocalists.

Movietone is an English post-rock band.
 They formed in Bristol, England in 1994.
 Core members are Kate Wright and Rachel Brook (now Rachel Coe).
 Brook was also a member of Flying Saucer Attack during the first few years of the band's existence, and Wright is also currently the bass player for Crescent.

Rachel's were an American chamber music group that formed in Louisville, Kentucky, in 1991.
 Former Rodan guitarist Jason Noble played music individually and referred to himself as Rachel's but then began collaborating with core members violist Christian Frederickson and pianist Rachel Grimes.
 The group's work was strongly influenced by classical music, particularly inspired by the minimalist music of the late 20th century, and its compositions reflect this.
 While the trio formed the core part of the band, the group's recordings and performances featured a varying ensemble of musicians, who played a range of string instruments (including viola and cello) in combination with piano, guitars, electric bass guitar, and a drum set that included a large orchestral bass drum.
 A key influence on the music of Rachel's was the music of the English composer Michael Nyman, whose music the group's work resembles in both instrumentation and compositional style.
Tricot Machine was a Canadian indie pop band, active from 2005 to 2012.
 Originally from Trois-Rivières, Quebec, the band's core members were Catherine Leduc and Matthieu Beaumont.

 At the 2009 Brit Awards they received the Brit Awards "Critics' Choice" award.
 The band's music is renowned for its dramatic and eccentric production and also Welch's powerful vocal performances.
