Being a huge AFI fan, I had to be the first to bring this news.
http://afireinside.net/temp.html is the band's new website. The URL will most likely change (or this site will just replace the old one on www.afireinside.net) but this is definitely official. There's a loop playing some new music, clicking on the trees brings up pictures of the band in the studio, and there are links to the old website, news, discography, and messageboard. According to the latest news, they're putting the finishing touches on the new album, which is rumored to be out in the first month or 2 of 2006. And to top it all off, the band is on KROQ Los Angeles today, and the station is going to premiere a new song this weekend.
I'm excited, knowing what this band is capable of producing. Sing the Sorrow was such a fantastic album that I still love every song on it, and I bought it like a month after it came out.
