Blue Man Group

Ah, the Blue Man Group. Few other blue characters inspire such divisiveness among their fan base and the as-yet-uninitiated—the only one that comes close is Cookie Monster, maybe Sonic the Hedgehog. Either way, these blue dudes are hitting Philly with their paint splatter antics for a limited run of dates at the Merriam. If this is your thing, don't miss out—there's not a ton of blue people willing to cover you in paint running around.
