BRUCE SPRINGSTEEN's exuberant new single 'High Hopes' features a RAGE AGAINST THE MACHINE-style wah-wah guitar solo and rhythm part from TOM MORELLO as well as what sounds like a full horn section.

The single will be officially released next week, but it leaked online today.

The song begins with a New Orleans carnival beat and a squall of feedback before a chunky acoustic guitar and Springsteen's teeth-gritted vocals kick in, followed by horns, accordions and an army of backing vocals on the chorus. The finished product sounds like an unexpected mix of the Seeger Sessions Band, Rage, the E Street Band and the Meters. Judging by this track, Springsteen isn't done with the musical boundary-pushing that characterized 2012's Wrecking Ball. 

Springsteen originally recorded "High Hopes" in 1995 during a brief reunion with the E Street Band. The song was written by Tim Scott McConnell in 1987, and he rerecorded it three years later with his band the Havalinas.

There is no official word about a new Springsteen album, but multiple sources tell Rolling Stone that one will be released early next year.
