Originally appearing on the album "11th Song", it was later re-recorded and released on their album "Home".  It was the band's only hit, peaking at number five on the "Billboard" Hot 100.  Outside the United States, the song topped the charts in the United Kingdom, and peaked within the top ten of the charts in Australia, Belgium (Flanders), Canada, Germany, the Republic of Ireland and Sweden. 11th Song is the debut album by alternative rock band Deep Blue Something.  It was released on Doberman Records in 1993. The Auteurs were a British alternative rock band of the 1990s, and a vehicle for songwriter Luke Haines (guitar, piano and vocals). Azurite is a soft, deep blue copper mineral produced by weathering of copper ore deposits.  It is also known as Chessylite after the type locality at Chessy-les-Mines near Lyon, France.  The mineral, a carbonate, has been known since ancient times, and was mentioned in Pliny the Elder's Natural History under the Greek name "kuanos" (κυανός: "deep blue," root of English "cyan") and the Latin name "caeruleum".  The blue of azurite is exceptionally deep and clear, and for that reason the mineral has tended to be associated since antiquity with the deep blue color of low-humidity desert and winter skies.  The modern English name of the mineral reflects this association, since both "azurite" and "azure" are derived via Arabic from the Persian "lazhward" (لاژورد), an area known for its deposits of another deep blue stone, lapis lazuli ("stone of azure"). The 440 Alliance is an American cello rock band from Arlington, Texas consisting of five cellists and a percussionist.  The group formed in 2004 and is known for their diverse approach to the cello, incorporating electric effects, turntables, piano, and mallet percussion.  They received national exposure on NPR's "All Songs Considered", the Drew Pearson Show on Fox Sports, and on Fox's musical reality show, "The Next Great American Band".  The group has performed at a number of private parties for celebrities including Troy Aikman (Former NFL Quarterback for the Dallas Cowboys), Jerry Jones (Dallas Cowboys owner), John Kirtland (Former drummer for Deep Blue Something and owner of Kirtland Records), Janine Turner (from Northern Exposure), members of the Dallas Symphony Orchestra, as well as the Dallas, TX movie premier for the film 'The Soloist' (starring Jamie Foxx and Robert Downey Jr.). Course of Empire is the debut self-titled album from the Dallas, Texas band.  The album was originally released on Dallas based Carpe Diem Records and sold over 5000 copies in the city alone.  All songs were written by Course of Empire and produced by David Castell (Blue October, Burden Brothers, Deep Blue Something, SouthFM).  The following August, Zoo Entertainment signed the band and reissued their CD with distribution through BMG Deep Blue Something are an American rock band who are best known for their 1995 hit single "Breakfast at Tiffany's" from their second album "Home".  "Home" achieved gold-record status; however, the band parted ways with Interscope and went on creative hiatus for several years, only releasing the follow-up "Byzantium" in Japan and some European countries.  They eventually signed with the Aezra label and released "Deep Blue Something" in mid-2001, breaking up shortly after.  With only one single to chart on the "Billboard" Hot 100, they are often considered a one-hit-wonder.  The band now has recently regrouped with all members at the end of 2014 and signed to John Kirtland's independent label, Kirtland Records.
