They announced a new album ages ago, they've played some of the songs live already. And they have a tracklist on their facebook. Some of the songs were written ages ago but never saw the light of day. If you haven't already I implore you to listen to their Rarities album, they have a lot of demos and unreleased songs on there. Also check out Buck Dharma's one solo album, Flat Out, and his three archives of all the songs you never heard.The BOC are still great, managed to catch them on the last UK tour. They announced another show, but they are opening for DP. I'm a big fan of DP but not of this line-up. Show is in November but will definately get postponed. The shows will eventually happen, hopefully we will have a new album by then.

Off topic maybe, but there's a lot of stuff you want to hear from this. On their now-abandoned old website they have a whole list of the names of songs they wrote, never performed, or did record but it was lost to the test time.
