To celebrate its annual switch to festive music of the Christmas season across its stations nationwide, iHeartMedia today announced the second annual iHeartRadio Holiday Special, a virtual concert hosted by Mario Lopez. This special event will feature Kelly Clarkson, Michael Bublé, Train and Pentatonix performing popular holiday classics. It will broadcast across iHeartMedia’s AC, Hot AC and Classic Hits stations nationwide and on the iHeartRadio app, and video stream on iHeartRadio’s YouTube and Facebook pages on November 24 at 7 pm ET.

This season, iHeartMedia’s annual station flip to Christmas music kicked off today (11/5) with more than 80 stations across the country broadcasting and streaming the season’s festive music from today’s biggest artists as well as holiday classics.

“Our listeners always anxiously await the day our stations flip to Christmas music,” said Tom Poleman, Chief Programming Officer for iHeartMedia. “Kelly Clarkson, Michael Bublé, Train and Pentatonix have some of the best songs of the holiday season, and we’re excited to have them perform on our show.”
