This past summer, Lexus staged two unique concerts in Britain using twelve LS 460s in place of an orchestra. These cars, with no modification or amplification, performed two pieces originally recorded by the London Symphony Orchestra, which you can now listen to at a Lexus site dedicated to it.
I really enjoyed the site, there’s a behind-the-scenes section with a half-hour documentary on the recording and development of the event, which is a very interesting watch. Also included are Video and MP3s of the original recordings. Top Notch.
