AOl just posted a Listening Party for the Prisoner of Azkaban soundtrack. I've got to say that I'm more than pleasantly surprised. After the first track rehash of Hedwig's Theme, so far it's been almost entirely new. John Williams hasn't rehashed from his other scores much either, least not the ones I'm familiar with. The tension building music almost has a '30s jazzy sound. (See the second track) Lot more of a Celtic influence, too. A more professional version of "Double Trouble" from the latest trailer.
