There is this song on Rock Band for a band called "Bang Camaro." I had never heard of these guys, but their style is totally '70s-'80s heavy metal... I thought they were from that era, until I found this video of them on YouTube:

From Wikipedia: "The band is composed of a bassist, a drummer, two guitarists, and anywhere from eight to twelve vocalists comprising a full choir of lead singers." That is so awesome. I believe their song names are rather ironic, as well... what a celebration of that music era!
