CASXIO are a quartet of funky musicians who fuse elements of rock with disco. If you are having a hard time imagining that merger check out their new single “Seventeen,” which is likely to be on my “Most Played” iTunes playlist soon. It reminds me of early Shalamar mixed in with The Vines. The group is out now touring in support of Yelle and they are set to wow the world around with their Four Songs EP,which is available on their website for free. Go get it and listen to one of 2009′s break-through acts.
