By David Ross\n\nThis happened just on a whim. I met Zack at an event and struck up a conversation with him. He told me that he was in town from San Francisco to support a film he did music for called, \u201cChocolate Mountain Metal.\u201d It\u2019s a short documentary, directed by Ryan Maxey and Danielle Davis that premiered at AFI DOCS in Washington, D.C. We talked about music, him being particularly fond of Brian Eno\u2019s \u201cMusic for Airports\u201d album, which an old podcast guest of maDCap also really loved. I then told him I record musicians in tunnels underneath Dupont Circle. And just like that, we were able to make the above audio happen. This took place on a calm Sunday morning and it was the perfect music for tunnels. \n\nTo listen to more of Zack\u2019s work:\nwww.zwrightsound.com\n\nSpecial thanks to Hiroshi Jacobs for having built such an amazing installation.
