Today, Soundcheck looks at the Obama inauguration through the lens of music. We’ll have a series of reports on the day’s musical performances, which include classical, gospel, choral and even marching band music. We talk with pianist Gabriela Montero and clarinetist Anthony McGill, who are performing a new piece by John Williams in the ceremony. And we get a review from Washington Post classical music critic Anne Midgette. Plus: analysis of the events of the day from WNYC hosts and reporters.
