They have three score albums, for MONSTER’S BALL, STAY and MACHINE GUN PREACHER. Also some other albums.
Seems like Tom Scott was/is a member, and that Mark Asche has left.

Interesting comment:
“Do you perceive the similarities with Hans Zimmer´s firm, the Remote Control Productions, where many composers are contributing “invisible”?
We are the opposite of Hans Zimmer´s company. We are not invisible ghostwriters hiding behind one persons name. Each of us is an evolved member of the composing team working with the filmmakers to score the film.”
