Hip hop is constantly evolving. That is part of it’s ongoing appeal; no one artist, group or sound can define it. It is a music that lives in the moment. To witness one of the latest innovations in the genre without fences, be sure to check out the the BYOB Tour making a bass-booming stop at Plant Zero on Friday, March 11. The showcase of here-and-now, Southern rhythm and rhyme features headline performances by Boog Brown and Yamin Sema from the Atlanta Georgia collective Working Class Music and tour mate Melaphyre Etheoryall. Hosted by local culture pushers Happily Natural, local turntablists DJ Sayeed and DJ Mike Kemetic will add indigenous ingredients to the the night’s kaleidoscope of hip-hopped soul, funk, rock and psychedelia that also includes sets by regional rappers JD Haze, TIff the Gift, Rubber Peeple and Nod Da God. Doors open at 8 p.m. Admission is $5-$10. For more information, call 397-1465 or visit happilynaturalday.com. plantzerocafe.com
