Sean Howard Kinney (born May 27, 1966) is an American musician, best known as the drummer and co-founder of the rock band Alice in Chains.

Kinney explained in the 2009 book Grunge is Dead: I almost didn't play on the record – they started rehearsing with the drummer from Mother Love Bone, Greg Gilmore.

[16] In 1996, Kinney joined singer Johnny Cash, guitarist Kim Thayil of Soundgarden, and bassist Krist Novoselic of Nirvana for a cover of Willie Nelson's "Time of the Preacher", featured on the tribute album Twisted Willie,[17][18] which also had Kinney playing drums for Jerry Cantrell's cover of "I've Seen All This World I Care to See".

[18] In the same year, Kinney played drums for Cantrell's first original solo song, "Leave Me Alone", featured on the soundtrack of the 1996 film The Cable Guy.

[22] Alice in Chains' bassist Mike Inez and Sponge lead vocalist Vin Dombroski joined the band soon after.

The band released their first and only album on May 18, 2001, a 6-track EP entitled Microfish,[23] and made their live debut at Endfest in Bremerton, Washington on August 4, 2001.

[24] Since 2009, Kinney co-owns the club The Crocodile in Seattle along with Alice in Chains' manager Susan Silver,[25][26] Capitol Hill Block Party co-founder Marcus Charles,[27] Peggy Curtis,[27] and Portugal.

[28] Soundgarden lead vocalist Chris Cornell personally asked Kinney to join him, Pearl Jam guitarist Mike McCready, Soundgarden drummer Matt Cameron, Screaming Trees drummer Barrett Martin and Guns N' Roses bassist Duff McKagan in the tribute show to the band Mad Season at Seattle's Benaroya Hall on January 30, 2015.

[30] The performance was released as a live album in August 2015, entitled Mad Season / Seattle Symphony: Sonic Evolution / January 30, 2015 / Benaroya Hall.

[33] In 2005, Kinney came up with the idea of reuniting with the other two surviving members of Alice in Chains, Jerry Cantrell and Mike Inez, to perform at 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,[34] and the band performed for the first time in 10 years at the K-Rock Tsunami Continued Care Relief Concert in Seattle on February 18, 2006, featuring guest vocalists singing Staley's parts.

[39] In 2013, Kinney added the initials "LSMS" on his drum kit, a tribute to Alice in Chains' late members Layne Staley and Mike Starr.

[45] The music video for the album's first single, "Grind", shows a three legged dog (similar to the one that allegedly used to chase Kinney) walking up a stairway with an elderly man.
