The haunting string theme to Mad Men may be his most widely known composition, but Ramble John Krohn, the hip-hop and electronic producer better known as RJD2, creates more than just trancy TV music. The Ohio native began his career DJing with rap group MHz and now is an in-demand producer for Massive Attack, Mos Def, and many others. Some tracks take a minimal approach with slight additions of funk, while others blend jazz instrumentals with hip-hop and electronic beats. And he’s not just a producer: Krohn also scored the graffiti video game Marc Ecko’s Getting Up: Contents Under Pressure and contributed to the cookbook I Like Food, Food Tastes Good. Tonight at 9:30 Club, he’ll highlight tracks from last year’s More Is Than Isn’t and leave the ’60s period pieces on Netflix. RJD2 performs with Christine Moritz at 7 p.m. at 9:30 Club, 815 V St. NW. $20. (202) 265-0930. 930.com.
