Harmonix has confirmed with us today that open beta registration for its Rock Band Network will open this evening. Once enrolled, link your rockband.com account to creators.rockband.com to begin uploading music, peer reviewing, and previewing tracks.
According to the developer, tracks by Jonathan Coulton and Billy Idol (as well as some Finnish death metal) will be among the tracks that are slated to appear on the Rock Band Network. Additionally, the Wall Street Journal is reporting that multi-platinum artists Creed and Evanescence will also have music on the service. Indie label Sub Pop's plans are also made a bit more clear -- expect music from The Shins, Flight of the Conchords, Mudhoney, Sleater-Kinney, and The Postal Service.
Harmonix says that the actual Rock Band Network Store won't be live "until we accrue a good base of content, though we're already really excited by what we have in the pipeline." Track prices will range from $1 to $3, set by the bands and track authors.
