Orlando's two pop group sensations, 'N Sync and the Backstreet Boys, will appear on a new benefit single, "Let the Music Hear Your Soul," set to arrive in stores on November 3.

The song, which was recorded by a group of vocal artists -- including Backstreet sibling Aaron Carter -- under the group name of the Bravo All Stars, has already charted in several European countries, according to "Billboard."

Proceeds from the U.S. release of the single will be donated to the Nordoff-Robbins Music Therapy Foundation, an organization that uses music to help treat autistic and other severely disabled children.

The benefit single is the most recent example of the Nordoff-Robbins foundation benefitting from the support of artists, which has long been a favorite of rock bands. Aerosmith, Madonna, Bob Dylan and Bruce Springsteen have previously contributed items for a charity auction, and bands ranging from The Who to ZZ Top have also lent their support.
