Mr. McGill was the Philharmonic’s first Black principal musician when he joined in 2014; he is currently its only Black player. He appears at David Geffen Hall and elsewhere as a concerto soloist, and is in a trio with his brother, Demarre McGill — the principal flute of the Seattle Symphony — and the pianist Michael McHale. In 2009, he performed at Barack Obama’s presidential inauguration. – The New York Times
