Hi,
I'm a moderator at Final Gear, a popular Top Gear fan site. I noticed several posts here regarding music heard on Top Gear, so I wanted to direct you guys to our music ID forum, were we try to list all the music heard in each episode. Many of the more obscure (indie, ambient) tunes have not been identified yet, so I'm hoping that some of you here might recognize them. We could use the help! Post in this thread if you recognize anything.

...at the link you'll find the current Season 12 as well as past seasons and sound samples of unknown bits.

Thanks!
