Ital & Halal return to Lovers Rock with 'Tower B,' an EP of enigmatic techno explorations. 'Shenzhen River' opens: an ominous, questing acid line stretches its tendrils around nocturnal atmospheres. 'From the Brink' counters with glints of warm melody. On side B, the title track unfurls with slithering percussion and a menacing drone. Ambient closer 'Where Exactly I Am' picks up the pieces, lost voices traveling across the stereo field, searching for answers through an endless pale haze
