Schoolhouse Punk Rock II
Dave Smith and Seth Frisbie-Fulton's Japan Punk Project has been gathering information about Japanese punk-rock bands since 1999. Granted, they only highlight 16 bands currently, but it seems that the listings include full personnel, contact, and discography information. Also featuring record reviews and a directory of labels and distributors, the service offers a tour schedule that hasn't been updated since 2001. Don't expect the content here to be that fresh, but it's certainly interesting. MP3's are scarce, but each band seems to have at least one RealAudio song online.
