Michelle and Christina Naughton

Next season, the identical twins in this up-and-coming piano duo will make debuts with orchestras in Houston and Philadelphia—though not before they drop by our Naumburg Bandshell for a free concert of 20th-century works: John Adams’s propulsive and winning Hallelujah Junction, and two-piano arrangements of Milhaud’s Scaramouche, Ravel’s La Valse and Stravinsky’s Rite of Spring. The first thousand people to show up to the bandshell get in free.
