Mike Kinsella (born March 4, 1977) is one of three Kinsellas (brother Tim Kinsella and cousin Nate Kinsella) involved in many Illinois-based bands. First recognized in the music scene in Cap'n Jazz, a big player in the refinement of post-emo indie rock, he has since stepped into many new projects. From Cap'n Jazz, he became part of Joan of Arc, a band taking a bit more of an abstract, experimental approach to the indie music where Cap'n Jazz left off. Wikipedia
