The Homewood Brass Consort is a quintet made up of Hopkins Symphony Orchestra brass players. This photo shoot was done in and around Shriver Hall (the HSO's primary performance venue) on Sept 15, 2008.
The group used these photos on their web site very soon after they were shot, and used them for years thereafter, until the web site disappeared in mid-2015. However, the images continue on their Facebook page, from 2014 forward.
