Studio X (formerly known as Bad Animals Studio and Kaye-Smith Studios) is a music and media recording studio on 4th Avenue in downtown Seattle, Washington, United States. Originally part of the Kaye-Smith Enterprises media conglomerate founded by Lester Smith and actor Danny Kaye, the studio was used to record commercials and musicians. The studio was re-launched as Steve Lawson Productions by Steve and Debbie Lawson in 1979. The sisters Ann and Nancy Wilson of the band Heart owned the studio from 1991 until 1997, and named it Bad Animals after their 1987 album of the same name. Artists such as Heart, Alice in Chains, Pearl Jam, Soundgarden, Nirvana, Queensrÿche, Mad Season, Foo Fighters, Audioslave, Aerosmith, The Beach Boys, Jerry Cantrell, Eddie Vedder, Duff McKagan, Johnny Cash, B.B. King, Radiohead, R.E.M., Deftones, Soulfly, Steve Vai, and Neil Young have recorded at the studio. History In 1991, Nancy and Ann Wilson of the band Heart entered into a partnership with Steve Lawson, who owned Kaye-Smith Studios where many of their 1970s hits, as well as their 1980 album Bébé le Strange, had been recorded. They upgraded the facility to the state-of-the-art, and renamed it Bad Animals Studio. The studio was named after Heart's 1987 album, Bad Animals. Ann and Nancy sold the studio back to the Lawsons in 1997, and it was renamed Studio X. Several of the Humongous Entertainment games were also recorded by Bad Animals Studios. In May 1993, Nirvana entered Bad Animals Studios to remix the songs "Heart-Shaped Box" and "All Apologies" for their album In Utero. The music video for Soundgarden's 1994 single "Fell on Black Days" was filmed at the studio. In 1997, Steve Lawson sold Bad Animals to Mike McAuliffe, Dave Howe, Charlie Nordstrom and Tom McGurk. In 1998, the Spice Girls recorded vocals for the song "Boyfriend/Girlfriend", their contribution to the South Park soundtrack at the studio. In 2001, Bill Brown recorded all of the music for Microsoft's Windows XP operating system with a live orchestra at the studio. On September 1, 2003, Seattle radio station KNDD 107.7 The End hosted a solo acoustic performance by Thom Yorke at Studio X. In October 2017, the studio was purchased for $21.6 million by Skanska, which plans to build a 346-unit multifamily tower with ground-floor retail in the building. On October 31, 2018, Studio X, now managed by Reed Ruddy, moved its location from Belltown to Capitol
