"Tenderness" will be released on May 31. The disc sees McKagan reflecting on his experiences traveling the globe over two and a half years on GUNS N' ROSES' "Not In This Lifetime" tour. Encountering heartbreak, anger, fear, confusion and divide on his travels during this tumultuous time in our world history, McKagan channeled a collective hurt into songs of monolithic power.

"We're becoming divided at a time when we need each other most," says McKagan. "When huge industries get replaced because of modernization, it's time to retrain and bolster up those who get swept aside. Homelessness and drug addiction are avoidable in this country if we come together and get private and public cogs turning together in a positive direction. We can at least try to tackle mental illness while we're at it. But alas, we stump and lie, point fingers and divide. We're way better than this. As a father, I must say and do something now because I love my girls and my wife, and I love my country, and I feel I must be strong and use my voice now, do it while I'm able or perhaps never get a chance ever again."

McKagan and Jennings began recording "Tenderness" a year ago, working out of Station House studios, located in Echo Park, California, where they wrote and recorded in-between McKagan's tour with seminal rock band GUNS N' ROSES and the release of Jennings's eponymous album, "Shooter". "Tenderness" features Jennings and his band along with appearances by The Waters and The Suicide Horn Section (which features Duff's brother Matt McKagan on trombone), amongst others.

More than a year later, they're gearing up to take these songs on the road for a North American tour that kicks off May 30 at TLA in Philadelphia.
