About 8 years ago, BMW used a pretty aggressive techno, almost industrial type song for a series of commercials. I have been trying for the past month to find out the name of it, but to no avail.

I will know the name when I hear it, but can't offer much more to help narrow it down.

I'm not sure we are talking about the same commercial and even if we are I'm not 100 % sure the group involved but I believe the music is from Tangerine Dream they also do sound tracks like [B][I]Thief (1981) James Caan (Actor), Tuesday Weld (Actor), Michael Mann (Director this information is from Amazon. One other possability is Crystal Method they have been reported to have done music to some commercials. They use some of Crystal Methods music during the Air Force Thunderbirds aviation demonstration, most of it is off their Vegas CD. Good luck and I hope you find your music.
