U.K. DJ crew Radioclit have far-ranging ears (along with a great name). They joined Malawian singer Esau Mwamwaya for last year's Internet freebie Esau Mwamwaya and Radioclit Are the Very Best, a mixtape combining originals with remakes of tracks by M.I.A. and Vampire Weekend. On Warm Heart of Africa, those acts return the favor with guest spots, alongside fat beats and Mwamwaya's warm vocals. The best tune is the title cut, with VW's Ezra Koenig. But the woozy slow-jam "Julia," among other tracks, proves the group's polyglot street jams are plenty catchy unassisted.
