Jack Milas and Oli Chang of the New York-based group, High Highs, assure us that the sky's the limit, with their towering, yet quaint billows of songs. What they also assure us is that there's no limit to the sky that they have available to them. It's all perpetual sky. It goes and goes. The blues and the grays can be forever ripped from their hangers, replaced by more of the same. Our eyes go wide at the canvas.
