Two great choirs and a number of great artists will join forces this June at Carnegie Hall for a concert tour called “Imagine a World – Music for Humanity.” The performance takes place on June 14, 2017, at 8 p.m. EDT. There will be a subsequent performance the next day at Washington National Cathedral.

The Dallas Street Choir, which is comprised of those experiencing homelessness, is joining forces with the Credo Choir to put on a historic event. According to Carnegie Hall archivist, Gino Francesconi, a “musical ensemble comprised solely of those experiencing homelessness” has never performed at the iconic concert venue.

If that wasn’t enough to excite you, the concert will also feature some of the great artists of the past and present. Composer Jake Heggie will join forces with famed mezzo-soprano Frederica von Stade and soprano Harolyn Blackwell to create some music for the event. Composer Stephen Schwartz will also participate. Von Stade will premiere Heggie’s new setting of “Spinning Song,” which has been dedicated to the Dallas Street Choir. He will also play piano during the piece.

According to the release, 300 tickets have been donated to the New York City Department of Homeless Services to allow the homeless community in NYC to attend for free.
