Chris Cornell will release Higher Truth, his first solo album since 2009’s Scream, tomorrow (Sept. 18). Before then, he’s sent fans on a treasure hunt in order to hear his latest song, but if you’d rather skip ahead to the finish line, you can stream “Worried Moon” now in the video up above (via Mashable).

Cornell began tweeting Higher Truth-related clues as part of his “Worried Moon” treasure hunt yesterday. The hints direct participants to this website and ultimately lead them to other hidden goodies, such as handwritten lyrics and an interview between Cornell and filmmaker Cameron Crowe discussing the inspiration behind the new song.

“Worried Moon” follows Higher Truth’s lead track and single, “Nearly Forgot My Broken Heart,” which recently received an accompanying Western-inspired music video.

The Soundgarden frontman’s solo tour kicks off Sept. 20 in L.A., with dates scheduled through the beginning of November. Cornell will wrap things up with a show in Austin on Nov. 2. Check out a complete tour itinerary at this location.
