Quoted from rosh:Do not judge the music from this stream. It did not do it justice. I listen to it all day long and barely recognized it on the stream. It is also missing two of the main tracks and a few of the mode tracks. While not everyone is going to love that there is a mix of music, I think most will find it festive when it should be, and rockin when it should be and drunk when it should be.
The main theme reminds me of early Playstation extreme sports games (snowboarding, ATV, etc). Of course, I like hard driving guitar riffs, progressive rock flair and even a little polka music so it's a match for me.
The composer, Matt Kern, has a very impressive portfolio of music for video games and slot machines. You may not like every theme in the game but this guy is a great composer. I think he's done a great job mashing up the Oktoberfest theme with a rocking soundtrack. The music for Houdini, which Matt also did, is amazing. I didn't really appreciate it fully until I started cranking it up at home. I really, really like what I'm hearing so far from Oktoberfest.
