Diversifying its already wildly eclectic roster, Type now unleashes a breezy indie band. It sounds like radio-lovin’ Chicago, but When the Air is actually the work of Hamburg-based Henning Wandoff and his like-minded collaborators. With 10 songs in 37 minutes, this is a near-perfect realization of skewed indie pop, with deftly placed, aurally engaging instrumentation and Henning’s voice, which glides from gruffness to sweetness, intermittently buttressed by that of a breathy girl. The air is warm, and Mountaineer shines brightly.
