The Tony Hawk games have always had interesting soundtracks, some of which exposed me to new artists who’s work I went on to buy afterwards, which is a good sign.

link goes to game not music
the music was done by Amon Tobin who received a copy of the game and was told to go to town with a sound track (so the story goes anyway)
the guy is one hell of a dj and the album is well worth owning in its own right.
