Flume fuses slick R&B with pounding electro-house beats to make radio-friendly tracks with everyone from silky-voiced George Maple to electro-soul master Chet Faker. “Tiny Cities”, featuring Beck, is a master class in minimalist beats, while “Smoke & Retribution”, boasting rapper Vince Staples, is a barnstorming hip-hop anthem with atmospheric synths and glitchy beats.
