One of the more exciting byproducts of the rap world’s current DJ Mustard fever is that it shines a light on the post-hyphy Bay Area producers that have been mining this kind of spare party music for long before even “Rack City” came along. One such MC is Roach Gigz, a spazzy and incredibly clever rapper who released the fourth volume of his Roachy Balboa mixtape series last week. The greyscale video for “Zombie,” a whirring highlight off Roachy Balboa: Round 4, features Roach Gigz rising out of a bathtub (creepily invisible to the young woman nearby) as he shouts out psychedelic and twisty one-liners. (Ex. “I should’ve been born in the sixties/ As a ‘Frisco hippie.”) Watch the video for “Zombie” above.
