If you’re thrown off by artists who zig when they’re expected to zag, you may be a bit taken aback by Chance of Rain. Halo’s first full-length release, 2012's Quarantine, turned heads by combining ambient-flavored electronics with a more conventional songwriting sensibility, as well as the Brooklynite’s own haunting vocals. So one might assume she'd take a similar approach on the follow-up. Instead, Halo has eschewed vocals almost entirely on her second album, letting her fingers do the talking. Her deftness at layering electronics in an artfully atmospheric way is undiminished, but these tracks aren’t all about ambient synthscapes. “Dr Echt” revolves around what sounds like a heavily processed electric piano, while the closing track, “-Out,” is an old-school acoustic piano piece. Halo brings some beats to the party too, firing up cuts like “Oneiroi" and the title tune with propulsive polyrhythms.
