Disney+ will live-stream Walt Disney World's EPCOT display Harmonious in honor of World Music Day June 21 at 9 PM ET. The special event—titled Harmonious Live!—will be hosted by Wicked Tony winner Idina Menzel, who voiced Elsa in Disney's animated musical Frozen and its sequel Frozen 2.  

The special event will feature Auli’i Cravalho from Disney's Moana (which has songs by Tony winner Lin-Manuel Miranda), along with a culturally diverse group of 240 artists and a live orchestra to celebrate the power of music with performances of classic Disney music.

TV watchers can also expect a mix of floating giant screens, choreographed moving fountains, lights, pyrotechnics and lasers, inspired by Moana, Aladdin, Coco, The Lion King, Mulan, and more. 

Watch the teaser trailer for Harmonious Live! below. 

Menzel made her Broadway debut in Jonathan Larson's rock musical Rent, originating the role of Maureen Johnson, before going on to star as Elphaba in the long-running musical Wicked and Elizabeth Vaughn in If/Then. Her screen performances include playing the recurring role of Shelby Corcoran in the Fox musical comedy Glee, Cecilia Carol "C. C." Bloom in the TV remake of Beaches, and Vivian in the latest adaptation of Cinderella, starring Billy Porter and James Cordon.

Following the live stream, the event will be available on Disney+ in the U.S. and Canada.
