With their mix of soulful, sample-based beats and tag-team vocals, hip-hop trio Rhymester helped bring rap music to Japan's mainstream. Backed by DJ Jin's production—which spans horn-backed strutters (“B-Boyism”) to squelchy electro (“Walk This Way”)—MCs Mummy-D and Utamaru trade verses, sounding laidback while pulling off swift wordplay. Inspired by old-school American hip-hop, they evoke the spirit of the genre while also building up shout-along hooks that will addict listeners of all stripes.
