iTunes’ “Live From Soho” series offers significant online and offline promotion, so I was keen to find a classical artist that would fit into this predominantly pop-alternative campaign.

In January 2010, Philip Glass became the first classical artist to make a recording at flagship Apple retail store in Soho. The store remained open throughout the performance, but more than 300 people filled the upstairs, standing in silence to hear more than 45 minutes of live, acoustic music.

The recording is available on iTunes, and includes a rare performance of Philip and Ira Glass performing the Wichita Vortex Sutra.
