On Saturday, sandwiched between my postcast conversation with P&C critic Joshua Rosenblum and a noontime encounter with Charleston Ballet Theatre’s final Brown Bag & Ballet performance, I ran into one of the Spoleto Festival Orchestra’s 113 amazing young musicians. Eliot Gattegno is a first-year saxophonist with the SFO who was hanging out at Kudu Coffee (natch) between gigs, and he was happy to gab for a few minutes about what it means to be in one of the best temporary orchestras in the world.
