Kamen, who died in 2003 at the age of 55 was a major league talent who was enormously successful in many musical endeavours. While attending the New York High School of Music and Art he formed the rock/classical fusion band the New York Rock and Roll Ensemble. He later attended Julliard and was a protégé of the incomparable Leonard Bernstein.
Michael Kamen became a go-to arranger and composer of popular music. He arranged the music and conducted the National Philharmonic Orchestra on the recording of Eric Clapton's 24 Nights. He wrote Bryan Adam's Oscar-winning song Everything I do (I Do for You). I think his arrangement is largely responsible for the success of the Eurythmics hit Here Comes the Rain Again.
Kamen wrote the scores of a couple of dozen Hollywood films including the Lethal Weapon series, Mr. Holland's Opus and X-Men.
The Band of Brothers music is remarkable. Kamen, himself, viewed it as a special project. He said, "I wrote this as a requiem for an uncle I never met. My personal quest on this project was to distill the beauty and heroism of the soldiers and their stories out of the war's devastation."
We are used to insistent, pulsing music beneath the action scenes in films. There is little of that in Band of Brothers. The battle scenes, full of the sounds of gun-shots, explosions and warriors yelling play without accompaniment. Music often plays instead during introspective scenes and in descriptive passages devoid of dialogue. With eight different directors working on the series, the decision to score the series this way must have been made jointly by the composer and executive producers Tom Hanks and Steven Spielberg.
Here is the main theme music for the series. If you'd like to hear more, I've also linked to a recording of the two Band of Brothers suites. The music is played by the London Metropolitan Orchestra, Michael Kamen conducting, of course.
