Fri. Jan. 22

 The punk rock revolution and post-punk era re-generated the idea of rock concert poster art. At Space 242, an exhibit of more than 100 rock posters called "POST THIS!" is up and ongoing, open on Fridays, but closing this Friday Jan. 22. It has splashy, neo-psychedelic rock posters from the 1990s into the present (Butthole Surfers, Meat Puppets, Pearl Jam, the Jesus Lizard, among them). It's open every 6:30-8. Some of the best-known artists showing their work are Lindsey Kuhn, Pete Cardoso, Joey Mars (in photo) Enemy Ink, Mike King, Brian Methe and Ben Wilson. . Incidentally, Space 242 celebrates a year in the, um, space in January of 2009. It's been the proud home of what some would call "low-brow" or pop surrrealist art - an alternative to the "fine art" galleries on Newbury street and elsewhere in the South End. Is the stuff for sale? You betcha.
