This weekend: Harbourfront’s annual Beats, Breaks and Culture goes heavy on the hip-hop with legendary New York MC Rakim and a unique tribute to Detroit beatmaker J Dilla; San Francisco house luminary Miguel Migs headlines an all-day party at Sunnyside Pavilion; rockabilly pioneer Sleepy LaBeef rolls into the Dominion on Queen; and Afrofest brings the sunny sounds of the continent to Queen’s Park.
