Hear Harlem Choir Rejoice

17 May ’21

One of my favorite stories to have had the opportunity to work on at The New York Times is an immersive project about Bethel Gospel Assembly, a Pentecostal church in Harlem called Hear A Harlem Choir Rejoice Again. It’s a moving story about the power of community and song in the midst of the pandemic by Tariro Mzezewa.

Music plays an important part of this experience, so please grab some headphones and listen to the binaural audio that I mixed within the streaming photogrammetry model of the sanctuary that we photographed. Here’s an article about the making of the story.

A fateful moment, for all to read, in the New York Times.

2 Apr ’19


In 2002, I had bad accident up in Alaska. It’s an experience that has shaped my life in more ways than I care to admit. As most can attest, I rarely discuss it publicly, but it is an event that has informed much of my work and the subtext of my health pursuits. Here it is for all to read, as told through my friend Jon.

Bear Call Mastering

I’m thrilled to announce that my new studio, Bear Call Mastering has opened in the beautiful Hudson Valley.

The acoustics of the new studio sound fantastic and there’s been a nice equipment upgrade, records will sound better than ever. In addition to mastering, we’re also adding audio services for artists and interactives, and post-production sound for films. Come visit, and inquire about our cabin in the hills!
