Local DJ/producer extraordinaire Rob Lemon has been busy as of late. When he's not helping to create tracks that make the top-five downloads on Beatport's progressive chart, he's organizing and playing at DJ nights all around town. In fact, this weekend you can catch him at two events at two venues. On Friday, April 6, head over to the Upstairs Lounge (3131 South Grand Boulevard; 314-773-3388 or www.upstairslounge.com) for a post-Winter Music Conference party. If you didn't make it to Miami, now's your chance to catch up on gossip and check out sets by Lee Foss and Lemon. The dish-and-dance session runs from 10 p.m. to 3 a.m., and there's a $5 cover. Then, on Saturday, April 7, Lemon opens for Bill Pile and Paul DeMatteo at Dante's (3221 Olive Street). Doors open at 9 p.m., and the cost of admission is $5 before 11 p.m. and $10 after.
