It’s not just for kids anymore: With the 20th anniversary of hiphop on the horizon, many die-hard b-boys have become grown men with responsibilities other than keeping up with the beatbox. In the shuffle to build careers and even raise families, loving the music often takes a back seat to getting paid in full. However, brothers like Asheru and Blue Black of the Unspoken Heard refuse to forsake the art form that essentially raised them. For these two clever MCs, it’s not all about the Benjamins; it’s about spending the time, effort, and—in the case of their self-financed EP, Cosmology—money to write and produce solid, thought-provoking material. Unspoken Heard will deliver beats, rhymes, and life from a mature yet hopeful perspective along with photographer Will Brent, fashion designer Andre Byron, and musicians Generation 2000, Amphibians, and Ras D, courtesy of Sol Innertainment. At 9 p.m. at the Capital Children’s Museum, 800 3rd St. NE. $10. (703) 922-5778. (Neil Drumming)
