Although Lushlife describes himself as a bedroom composer, the MC/producer has been quietly crafting a body of recordings that belie the dimensions of his small South Philadelphia workspace. His latest, Plateau Vision (featuring Heems of Das Racist, Memphis rapper Cities Aviv, ex-Titus Andronicus member Andrew Cedermark, et al), is a contemplative hiphop LP, balancing hazy cassette fragments with big-room hiphop. “Big Sur” finds Lushlife weaving a weirdo hidden-America-as-Philly-slang vibe, while producer and labelmate Botany splices together a beat that’s as indebted to J Dilla as it is to Jandek.
