It's shaping up to be a pretty busy week, with significant shows somewhere every night. Tonight it's Chromatics at O'Leaver's with Black Guys? Who are these Black Guys? None other than Darren Keen of The Show is the Rainbow with Jim Schroder (Mr. 1986), Javid Dabestani (Bright Calm Blue, Broken Spindles) and Brendan McGinn (Her Flyaway Manner). No idea what they sound like. Keen describes them as a "rock band." Chromatics record on Troubleman Unlimited, so expect arty noise mixed with electronics. $5, 9:30.
