threw his bass into the air in frustration after suffering equipment failure, and then stormed off the stage. The band retreated, with Cornell returning to end the show with a solo encore. On April 9, 1997, the band announced it was disbanding. Thayil said, "It was pretty obvious from everybody's general attitude over the course of the previous half year that there was some dissatisfaction." Cameron later said that Soundgarden was "eaten up by the business". The band released a greatest hits collection entitled A-Sides on November 4, 1997, composed of 17 songs, including the previously-unreleased "Bleed Together", which had been recorded during the Down on the Upside recording sessions. Post-breakup activities (1998–2009) Cornell released a solo album in September 1999, entitled Euphoria Morning, which featured Matt Cameron on the track "Disappearing One". By May 2001, Cornell joined the platinum-selling supergroup Audioslave with Tom Morello, Tim Commerford and Brad Wilk, then-former members of Rage Against the Machine, which recorded three albums: Audioslave (2002), Out of Exile (2005), and Revelations (2006). Cornell left Audioslave in early 2007, resulting in the band's break-up. His second solo album, Carry On, was released in June 2007, and his third solo album, Scream, produced by Timbaland, was released in March 2009, both to mixed commercial and critical success. Cornell also wrote the lyrics and provided vocals for the song "Promise" on Slash's debut solo album Slash, released in 2010. Thayil joined forces with former Dead Kennedys singer Jello Biafra, former Nirvana bassist Krist Novoselic, and drummer Gina Mainwal for one show, performing as The No WTO Combo during the WTO ministerial conference in Seattle on December 1, 1999. Thayil contributed guitar tracks to Steve Fisk's 2001 album, 999 Levels of Undo, as well as Dave Grohl's 2004 side-project album, Probot. In 2006, Thayil played guitar on the album Altar, the collaboration between the bands Sunn O))) and Boris. Cameron initially turned his efforts to his side-project Wellwater Conspiracy, to which both Shepherd and Thayil have contributed. He then worked briefly with the Smashing Pumpkins on the band's 1998 album, Adore. In 1998, he played drums for Pearl Jam's Yield Tour following Jack Irons's departure, and later joined Pearl Jam as an official member. He has recorded six albums as the band's drummer: Binaural (2000), Riot Act (2002), Pearl Jam (2006), Backspacer (2009), Lightning Bolt (2013) and Gigaton (2020). Cameron also played percussion on Geddy Lee's
