This week, NYCB Music Director Andrew Litton leads us on a promenade through the Modest Mussorgsky score to Alexei Ratmansky's 2014 ballet Pictures at an Exhibition. Beginning with a little background on the composer's short but complicated life, colored by contemporary critiques of his "disregard" for musical conventions, Litton is joined by Piano Soloist Stephen Gosling as he demonstrates the ways in which Mussorgsky captured the subjects of a beloved artists' paintings in remarkably challenging piano pieces.
