On his years off from making beats for Aesop Rock and others, Blockhead has assembled a group of instrumental LPs that stands solidly on its own, despite the generally shoddy reputation of instrumental hip-hop full-lengths over the past decade. The Music Scene adds new knots to Blockhead’s sly, ironic take on boom-bap, incorporating shifting structures that spiral into changing tempos, half-remembered snippets of soul horns and gnarly old guitars, and occasional drifts into hazy, shimmering psychedelia. Sadly, this fog thickly enshrouds the back half of the disc as the tempos stagnate, rendering it inert and crying out for a shot of adrenaline: paging Dr. Aesop Rock?
