A remix album, Becoming Remixed, followed in 1998. Howe and Corner then developed their own studio, also called Line of Flight after their earlier production work, and began sessions for the second Sneaker Pimps album. Kelli Ali had taken a break after the Becoming X tour and was away traveling, so Corner sang on the new demos. When Ali returned, she was told by Howe and Corner that her voice was no longer considered suitable for their new music, and that Corner's voice was a better fit. Due to other ongoing personality conflicts and the band's concern about being stereotyped as a faddish female-fronted trip-hop act, Ali was fired and Corner took over on lead vocals. This significant lineup change caused Virgin Records to drop the band. Their second album Splinter was released in the UK on Clean Up Records in 1999, and failed to match the commercial success of Becoming X. New songs were premiered during a 2001 European tour opening for Placebo. Their third album Bloodsport was released on Tommy Boy Records in 2002. Howe and Corner also gained notice by writing and producing for other artists, including Natalie Imbruglia, and for remixing songs under the name Line of Flight. In 2002, Joe Wilson and Dave Westlake left Sneaker Pimps. In 2003, a fourth Sneaker Pimps album was demoed but shelved. The album, which started as the soundtrack for an abandoned indie film project called Blind Michael, is referred to in fan circles as SP4. Corner then launched the solo project IAMX, which included several songs from the SP4 project. After some additional cancelled projects, in 2006 Howe and Corner recorded some new demo tracks, commonly referred to as SP5 demos, with an unidentified female singer that turned up on a MiniDisc found in a bar in Russia. The tracks were leaked online and were later confirmed to be legitimate new Sneaker Pimps songs. After several years of side projects, Howe hinted in 2015 that Sneaker Pimps may reform. Corner confirmed the reunion in 2016, and as of early 2019 they were reportedly working on a new album. Deluxe box sets of previous albums and two new studio albums were announced to be released variously across 2021. Date has been pushed back since news was released to an unknown time frame. In May 2021, the band announced a new album entitled Squaring the Circle. The album was produced
