Sneaker Pimps founding member Chris Corner began performing as the dark electro-pop persona IAMX in 2004. Named after the Sneaker Pimps album Becoming X, Corner had effectively become "X," which he described as an ever-changing variable. Adopting the characteristics of synth pop and new wave acts like New Order, the Cure, and Depeche Mode and adding a greater sense of theatricality, Corner's work as IAMX represented a notable departure from his work with the Sneaker Pimps. Moving from the pounding synth-rock of 2004 debut Kiss + Swallow, albums such as 2009's Kingdom of Welcome Addiction incorporated elements of dark cabaret. 2015's Metanoia, a heavy electro-industrial effort, was followed by more experimental releases like Unfall (2017) and Machinate (2021).

Corner's first full-length as IAMX, Kiss + Swallow, was released on Recall in 2004; many of the songs on the debut were originally written for a fourth Sneaker Pimps album that never materialized. His sophomore album, The Alternative, and a live album from the subsequent tour (Live in Warsaw) followed in 2008. In 2009, Corner released Kingdom of Welcome Addiction, which featured a darker, harder-edged sound, and included an inspired guest spot by Imogen Heap. A remix album -- the anagram Dogmatic Infidel Comedown OK -- was also released the same year. After issuing a fourth album, the icy, dance-tinged Volatile Times (2011), IAMX reunited with Jim Abbiss, who worked with Sneaker Pimps on Becoming X, and released The Unified Field in March 2013. The following year, Corner's compositions became an integral part of the mood of the award-winning television show How to Get Away with Murder, soundtracking the drama through its first four seasons.

In late 2015, he released the dramatic Metanoia, a sinister, dubby update of his usual sound. As with his previous works, the album's themes featured a dark, vampirish sensibility and dealt with topics like sexual fluidity, androgyny, emotional darkness, and decadence. Two years later, he issued the mainly instrumental techno album Unfall. In 2018, Corner recruited Kat von D for harmonic vocal contributions to his eighth effort, Alive in New Light. Acoustic album Echo Echo appeared in 2020, and Machinate, one of his most experimental releases, arrived in 2021. The live recording Mile Deep Hollow Tour 2019 surfaced in 2022. ~ Neil Z.
