It’s that time of year again!

On Wednesday, NBC will air its annual Rockefeller Center tree lighting ceremony — and PEOPLE can exclusively announce that Moana star Auli’i Cravalho, Harry Connick Jr., Seal and Train are set to perform at the festive celebration. The stars join a previously announced lineup of artists including Gwen Stefani, Brett Eldredge, Jennifer Nettles, Leslie Odom Jr., Pentatonix and the Tenors.

Today anchors Matt Lauer, Savannah Guthrie, Hoda Kotb, Al Roker and Lester Holt will host the 85th annual holiday special, which will celebrate the lighting of a 75-ft. tall, 50-ft. wide Norway Spruce from State College, Pennsylvania.

The tree — which weighs 13 tons and is around 80 years old — will be adorned with more than 50,000 multi-colored LEDs and topped with a stunning Swarovski star made up of 25,000 crystals and one million facets.

The tradition of the Rockefeller Christmas tree dates back to the Great Depression, when the inaugural tree was decked with 700 lights in 1933. The gathering was enhanced in 1936 with the opening of the Rockefeller Plaza outdoor ice-skating pond, and NBC televised the tree lighting for the first time in 1951.

NBCUniversal is partnering with the Arbor Day Foundation for the “Green Is Universal” holiday campaign by supporting tree-planting efforts to promote recovery in disaster-stricken areas brought on by the 2017 hurricanes Harvey, Irma and Maria.

Christmas in Rockefeller Center airs Wednesday at 8 p.m. ET on NBC. Prior to the primetime telecast, an additional live hour of the special will be broadcast on select NBC stations (check local listings).
