Passages:
"Sing It Back" is a song written and performed by Moloko (Róisín Murphy and Mark Brydon).  It first appeared in its original version on Moloko's second album, "I Am Not a Doctor"; it was released as a single on 15 March 1999, reaching number 45 on the UK Singles Chart.  The song experienced chart success after it was remixed by DJ Boris Dlugosch, peaking at number four in the UK in August 1999.  Murphy had started writing the lyrics while clubbing in New York City, and knew the song was at heart a dance track, but the group wanted to record it in a different artistic fashion for its album version. Overpowered is the second solo studio album by Irish singer and songwriter Róisín Murphy.  It was released on 11 October 2007 by EMI.  Receiving widespread critical acclaim, the album was more commercially successful than its predecessor, "Ruby Blue" (2005), debuting at number 20 on the UK Albums Chart with 9,656 copies sold in its first week.  "Overpowered" was shortlisted for the 2007 Choice Music Prize in Murphy's native Ireland.  As of May 2015, the album had sold 65,532 copies in the United Kingdom. Hot Streets is the tenth studio album (twelfth overall) by the American band Chicago, released in 1978.  In many ways, "Hot Streets" marked the beginning of a new era for the band, turning to disco music, a move which would be derided in retrospect.  It was also the band's first album with all-new material released since their second that didn't have a numbered title.  It was also the first album not to feature original guitarist/vocalist Terry Kath, who died from an accidental self-inflicted gunshot wound in January 1978.  He was replaced by Donnie Dacus on this album. Terry Alan Kath (January 31, 1946 – January 23, 1978) was an American musician and songwriter, best known as the original guitarist, one of the lead singers and founding members of the rock band Chicago.  He has been praised by the band for his guitar skills and Ray Charles-influenced vocal style. Ruby Blue is the debut solo album of Irish singer Róisín Murphy, released by Echo Records on 13 June 2005 (see 2005 in music).  After she and Mark Brydon dissolved their electronic duo Moloko, Murphy began working with producer and musician Matthew Herbert, known for his experimental work in jazz and electronic music.  The songs were first released through three extended plays and were then compiled into a studio album. "25 or 6 to 4" is a song written by the American musician Robert Lamm, one of the founding members of the rock/jazz fusion band Chicago.  It was recorded in 1969 for their second album, "Chicago", with Peter Cetera on lead vocals.  The album was released in January 1970 and the song was edited and released as a single in June of that same year, climbing to number four on the U.S. "Billboard" Hot 100 chart and number seven on the UK Singles Chart.  It was the band's first song to reach the top five in the U.S.  This recording features an electric guitar solo using a wah-wah pedal by Chicago guitarist Terry Kath, and a lead vocal line in Aeolian mode.  It has been included in numerous Chicago compilation albums. "Let Me Know" is a song by Irish singer Róisín Murphy from her second studio album, "Overpowered" (2007).  The song was written and produced by Murphy and Andy Cato.  It was released on 8 October 2007 as the album's second single.  "Let Me Know" reached number 28 on the UK Singles Chart, becoming Murphy's highest-peaking solo single to date. "Colour My World" is a song written by American musician James Pankow, one of the founding members of the rock/jazz fusion band Chicago.  Part of Pankow's "Ballet for a Girl in Buchannon" song cycle/suite, it was recorded for their second album "Chicago", also called "Chicago II" (1970).  Terry Kath sings the lead vocal, and Walter Parazaider performs the highly recognizable flute solo. Róisín Marie Murphy ( ; ] ; born 5 July 1973) is an Irish singer-songwriter and record producer.  She first became known in the 1990s as one-half of the UK trip hop duo Moloko with her partner Mark Brydon.

Her second solo album, "Overpowered", was released in 2007. Irish singer and songwriter Róisín Murphy has released four studio albums, one live album, five extended plays, 26 singles (including nine as a featured artist) and 14 music videos.
