Ashley Anderson a.k.a. Katalyst got 2011 off to a good start, teaming up with Steve Spacek for their Space Invadas project. As great as that full-length was, it had been four years since his What's Happening album caused seismic tremors within speakers and headphones worldwide. Thankfully, Katalyst has come through with the long-awaited follow-up, Deep Impressions. It's a collection of songs that feels more like an expertly compiled mix tape than an album, playing fast and loose with genre divisions. Clocking in at 45 minutes from beginning to end, it's the quintessential Side A of a treasured road trip cassette that flies through the many influences keeping Katalyst inspired these days.
