The same goes for Oval’s performance Friday at the MCA Chicago, part of the Empty Bottle and The Wire’s Adventures in Modern Music festival. Impressive in small doses. Tedious at length. Oval seemed to be mixing up the elements of his music, adding a bit more of a beat at times, but never pausing long enough between “songs” for the audience to applaud … or do whatever it might do. As with anyone who performs music on a laptop, it was impossible to know what Oval was doing … checking email while he was letting iTunes play his tracks? No, probably not. But the performance was so minimal, it was hard to say.
