Saturday marks five years since the Prhymemates put out a public call to revitalize the city’s stagnant hip-hop scene. They’ve since been successful in unifying the city’s talented graffiti artists, breakdancers, DJs, beat makers, and rappers — their most notable endeavor the annual “Clogged Caps” aerosol-art festival. The highlight of Saturday’s celebration is an appearance by world-renowned graffiti artist Cope2, visiting from the Bronx for a meet ’n’ greet and live painting performance. The night begins at The Yard (meetin’) and ends at Rock Bottom, where Cope2 will be painting alongside Houston’s Coloroner and SA’s LAWS and RTDk crew, in the mix with DJs Donnie Dee, Tech-neek, and Sean Cee.
