I've been on a hip-hop wave lately and this one gets into the on-repeat selection for sure.
Found US rapper Darius randomly but his "Buzzin" got me right away - his effortless but diverse flow & clever bars on top of boom-bap beats & jazzy samples (courtesy of producer tecwav) are pure perfection.
The song was created for the 50th anniversary of hip hop and I think it pays its tribute in just the right way.
