Keith Abrams has been drumming for Kayo Dot since Coyote as far as I know. He also plays for a band called Time of Orchids. Tim Byrnes plays trumpet on a lot of Kayo Dot's releases. Gamma Knife, Coyote, Hubardo, but he has his own band called Hazel-Rah. Not sure about Chuck Stern, but considering his name he's definitely the one that started this side project.
