Ambient Music: On the Go

Not all ambient sounds are best for quiet contemplation. This collection of tracks from new age legend Vangelis, jazz outsiders Penguin Cafe Orchestra, and avant-electronic artists Autechre and Tim Hecker don't just drift but ebb and flow. It's a soundtrack that will feel as welcome late at night as it will accompanying your morning commute, a brisk stroll, or a long highway drive.
