CITYWIDE Thousands of bands are in town for CMJ this week. Which shows are you going to? Brooklyn365 has mapped out the Brooklyn venues, Brokelyn listed their picks for free shows, and our intern named a few she’s psyched to see. BB Contributor Georgia Kral, who curated our excellent Northside Festival showcase, had her official CMJ showcase earlier this week, but on Friday she’s got another stellar lineup with Rose Quartz at Shea Stadium, including Fluffy Lumbers ($7, no badges, 8pm, 20 Meadow St., East Williamsburg). She’s also listed her CMJ picks on her blog, MME.
