Who would have thought that the coolest Friday-night party around would be at a stodgy art museum? But sure enough, on the last Friday of every month, the Denver Art Museum turns itself into a lively all-ages club, complete with local DJs or bands, a cash bar and a host of kooky activities — guided meditation in the Asian galleries, séances surrounded by selections from the Louvre, pedicure operations painting miniature artwork on your toes — that are sure to get those cranky old curators bristling behind their bifocals. The events are free with the normal price of admission, and they end by 10 p.m. — leaving you plenty of time to hit the town and act like the drunken buffoon you really are, knowing that you've already gotten your fill of high-falutin' culture.
