Since the middle of the 2000s, The Glitch Mob have taken bass music to the extreme, banging out synthesized jams that bounce like a hip-hop version of Giorgio Moroder. Drink the Sea, however, may be an attempt to evolve past talented followers like Pretty Lights. Instead of jacking up the beats, they've composed an electronic symphony. On tracks like "A Dream within a Dream" and "Animus Vox," they stretch and expand a motif for five minutes or so, occasionally ratcheting up tension with screaming melodic notes and "keytar" solos. Drink the Sea sounds delirious — it effectively transports instrumental hip-hop to a rave context — but that's part of The Glitch Mob's appeal.
