SOUNDGARDEN singer Chris Cornell's new single, "Nearly Forgot My Broken Heart", has exploded on the radio airwaves, becoming the most added track this week at the active rock, mainstream rock and adult alternative formats. The song is taken from Cornell's fourth solo studio album, "Higher Truth", which arrives on September 18.

Cornell told The Pulse Of Radio that the album, which is mostly acoustic in nature, was inspired by the solo acoustic tours he's done over the past few years. "It has been such a rewarding thing to do that I wanted to write an album of new material that essentially supported that and make it a living thing, as opposed to it being nostalgia, you know, and just going out and playing songs from yesterday," he said.

The deluxe version of "Higher Truth" will contain four bonus tracks.

The new disc follows up Cornell's last solo studio effort, 2009's urban pop-tinged "Scream". The Timbaland-produced set sharply divided fans.

Cornell will begin a tour in support of "Higher Truth" on September 18 in San Diego, winding down on November 4 in Phoenix.

The singer has also started working on material for the next SOUNDGARDEN album, which will follow up 2012's "King Animal".
