A quick overview of the Rockstar: Supernova contestants with links
The contestants official websites are down already, but the internet is bigger than that. Following are websites with mp3s, videos and/or photos of the contestants for Rockstar: Supernova. All finalists have established musical careers... OBVIOUSLY. Well, not obviously... but unlike the INXS contest which had the completely unknown and eventual winner and now MTV superstar J.D. Fortune, all these folks have some type following and presence in the music industry prior to the show.

and what of the INXSers?

Will Seabrook's site is down, but he has a Myspace Music.
Marty Casey and The Love Hammers are going strong, so is Suzie McNeil and Heather Lutrell.
Tara Slone is still rocking as is Mig Ayesa (although he's been in the studio for a new EP since Jan 2006. Daphna Dove's got a myspace which also links to a sexy music video. Neal's Bona Roba are also still chugging along and everyone's favorite Jordis Unga hasn't updated her site in forever, but it does have song available if you join the mailing list.
