Microsoft is happy to advertise that Forza Motorsport 4 features the return of award winning composer Lance Hayes. Lance's music in Forza 3 was apparently quite well received, as the soundtrack won an award from G4 TV, being marked as one of the 10 best electronic albums of 2010. Fancy.
Lance Hayes has produced 19 different tracks for use throughout the games interface and races, clocking in at over 100 minutes worth of content. Lance is apparently known for being a diverse composer, and it sounds like some of his stuff is my style (acid jazz makes an appearance in Forza 4.) I'm an outdated racing fan, though. When I think racing game soundtracks I hear the crazy music from old Sega racers. I'm sure all of you know that Forza Motorsport 4 is out today, and for any of you curious about Forza's musical style you can download the older soundtrack from iTunes.
