Yeah, Nick (guitar & vocals) is a doctor. Caught up with him at the Foxing show. Castevet played a "final show" with Toe back in November. But he said it's a very loose "final" show, and they'll probably play again. Basically yeah, he works 12 hour shifts at a time and doesn't have a lot of time for music.
He also played drums for Stay Ahead of the Weather, which they are hopefully recording a full length sometime in the future.
