Circles End is a Norwegian progressive rock band who started up in 1994 as a cover band named Venture.
 They renamed their project Circles End and started to write their own songs.
 They released their first EP in 1998 which was simply called "Circles End".
 Though the EP was well received, the band remained unsigned, so they pooled together their resources and recorded the full album "In Dialogue With The Moon" which was released in 2001.
 This album was also well received by the European progressive rock music press, but was somewhat neglected by the music industry.
 Around this time the band had a major line-up change and added a new keyboardist and bassplayer (in addition a guest saxophonist was added, not becoming a full member of the band until 2004).
 Circles End went into studio once more in 2003 to record their second full length album.
 A 7" single from the album, containing the songs "Echoes" and "Longshot" was released and it got the attention of the Bergen-based record company Karisma.
 The band signed with Karisma and released the full album from which the single had originated from.
 It came in 2004 and was called "Hang On To That Kite".
 Circles End also went on a tour of Norway after releasing this album.

Susumu Hirasawa (平沢 進 ) (born April 1, 1954) is a Japanese musician and composer.
 In the fifth year of elementary school, Hirasawa took up the electric guitar, inspired by the surf and instrumental rock bands he heard on the radio and on TV, later joining his junior high school's band.
 In 1973 he formed Mandrake, a progressive rock band that incorporated elements from heavy metal and krautrock.
 Being one of the few Japanese progressive rock bands of its time, Mandrake achieved little success and released no albums during its lifetime.
 After discovering punk rock and working on synthesizer-heavy projects, Hirasawa felt that progressive rock became just for entertainment and decided to reform the band as the electronic rock band P-Model in 1979.
 Originally met with success, they turned to decidedly uncommercial post-punk and experimental rock after Hirasawa went through an averse reaction to his fame.
 With Hirasawa at the forefront, the band went through various lineups and achieved some popularity in the Japanese independent music scene.
