LONDON — Hollywood composer Michael Kamen has signed an exclusive contract with Decca, a Polygram record label.Kamen’s first album for the label will be a 12-track CD featuring selections from his scores for “Robin Hood: Prince of Thieves,” “Mr. Holland’s Opus,” “Don Juan DeMarco” — specifically the song “Have You Ever Really Loved a Woman?” — “Circle of Friends,” “Crusoe,” “The Next Man,” “The Winter Guest,” “Highlander,” “Die Hard” and “Brazil.” Proceeds from the album will go to Mr. Holland’s Opus Foundation, which supplies instruments to schools in the U.S. In 1998, Decca will release Kamen’s “Concerto for Electric Guitar and Orchestra,” which was composed for Eric Clapton, and his as-yet-unfinished “The Millennium Symphony” in 1999, but will not necessarily release his future film soundtracks. The new version of the guitar concerto will be performed by Japanese guitarist Hotei Tomoyasu. Over his 20-year career, Kamen has recorded for several labels; Decca will now handle all non-soundtrack releases for an undisclosed period. Decca product is released on the London label in the U.S.
