Although never officially disbanding, Alice in Chains was plagued by extended inactivity from 1996 onwards due to Staley's substance abuse, which resulted in his death in 2002. The band reformed in 2005 when drummer Sean Kinney had the idea to reunite the surviving members to perform a benefit concert for the victims of the tsunami disaster that struck South Asia in 2004. On February 18, 2005, Cantrell, Mike Inez and Sean Kinney reunited to perform for the first time in 10 years as Alice in Chains at the "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, Wes Scantlin from Puddle of Mudd and Ann Wilson of Heart. A few months after that concert, the band called their former manager Susan Silver and Cantrell's manager Bill Siddons and said they wanted to tour as Alice in Chains again.
