In 2005, Sean Kinney came up with the idea of doing a benefit concert for the victims of the tsunami disaster that struck South Asia in 2004. Kinney made calls to his former bandmates, as well as friends in the music community, such as former Alice in Chains manager Susan Silver. Kinney was surprised by the enthusiastic response to his idea. On February 18, 2005, Jerry Cantrell, Mike Inez, and Sean Kinney reunited to perform for the first time in nine years at "K-Rock Tsunami Continued Care Relief Concert" in Seattle. The band featured Damageplan vocalist Pat Lachman, as well as other special guests including Maynard James Keenan of Tool and Ann Wilson of Heart. A few months after that experience, the band called Susan Silver and Cantrell's manager Bill Siddons and said they wanted to tour as Alice in Chains again.
