Performers from the music, dance, drama, and Preparatory divisions of the Juilliard School are performing throughout June at Hearst Plaza and Damrosch Park as part of Lincoln Center’s Restart Stages series of outdoor concerts. A June 2 open house will feature opera arias, song repertoire, chamber music, and a dance choreographed by Bobbi Jene Smith, with student performers from multiple Juilliard departments. Performances on June 3 will include the Juilliard Brass Ensemble conducted by Joseph Alessi, principal trombone of the New York Philharmonic, and selections from Handel’s Teseo, performed by singers from the Ellen and James S. Marcus Institute for Vocal Arts and members of the period-instrument ensemble Juilliard415, conducted by Gary Thor Wedow with concert staging by Stephen Wadsworth. Programs on June 5 and 12 will feature chamber ensembles from Juilliard’s Preparatory Division. The Preparatory Division, led by Weston Sprott, includes students from Juilliard Pre-College and the Music Advancement Program (MAP). Juilliard alumnus and faculty member Emanuel Ax will host and perform at a June 10 piano showcase. Additional, unannounced pop-up performances will take place in the Alice Tully Hall lobby, with sound amplified outside.
