"Nearly Forgot My Broken Heart" is the first track to be released from the Soundgarden singer's new solo album, "Higher Truth", which is set for release on September 18 via Universal Music Enterprises (UMe). The song opens with acoustic guitar and is said to be a far cry from the material that Cornell recorded on his last solo album, 2009's Timbaland-produced "Scream".

Starting today fans can pre-order the deluxe version of the highly anticipated album, which contains four bonus tracks.

Produced by Brendan O'Brien (Bruce Springsteen, Pearl Jam, Neil Young), "Higher Truth" showcases Cornell's constant evolution as a master songwriter, lyricist and musical craftsman — telling human stories, which transcend musical genres. Inspired by the stark arrangements of musicians like Nick Drake, Daniel Johnston and "White Album"-era The Beathles, Cornell creates a musical universe unlike anything he has done before.

Fans who preorder the album on iTunes will receive "Nearly Forgot My Broken Heart" as an instant download.
