Tommydski will probably be the best person on this board to consult about anything Kinsella-related, and I haven't really given anything from Joan of Arc a listen. However, if you haven't yet, I strongly encourage you to find the Make Believe albums. That band plays some of the best math-rock I've heard in years. Going to the Bone Church and Shock of Being are pretty ace; you could start with them.
(as an aside, I heard this band the other day called This Town Needs Guns, which just sounded like a non-Kinsella version of Owls. Not rad. They even have "In the summer of 2008 a rumour circulated that guitarist, Tim Collis, was taught to play by Victor Villareal (Owls, Cap'n Jazz), something which is yet to be confirmed or denied by the band" in their wikipedia entry.)
