Kendrick Lamar's purifying hip-hop narratives are equivalent to a long read. It's no surprise, then, that his video for latest track "Alright," taken from his second album To Pimp a Butterfly, is an extended rumination on the social issues preoccupying his work: discrimination, apartheid and police brutality. Featuring chopped-up snippets from others tracks from the album, "u," "Hood Politics" and the formerly never released "Cartoon & Cereal," the black-and-white meditation was brought to life by director Colin Tilley and The Little Homies.
