Rockstar has posted an audio preview from the PSP version of Chinatown Wars. You can listen to it below:

"We're proud to announce the addition of the biggest Metal outfit never to hit the big time and one of the greatest stories in rock'n'roll: Anvil. A one-time inspiration and influence to bands like Metallica, Motorhead and Slayer, Anvil were on the precipice of Metal superstardom when a series of unfortunate events cast them into relative obscurity."

Rockstar has promised more soundtrack details next week, so stay tuned!
