MTV, VH1, and Rolling Stone included an item indicating that Mackay had died as a result of a heroin overdose in the 1970s. The origin of this story is unknown, but music journalist Nick Kent reported the "fact" in a piece on Pop in the mid-1970s. According to Alexis Petridis, "Kent had apparently misheard the lyrics of Iggy Pop’s 'Dum Dum Boys,' which mentioned the death of Stooges roadie and bassist Thomas 'Zeke' Zettner." A second rumor circulated following the AIDS-related death of a San Francisco-based marathon runner and author who shared Mackay's name. Scott Nydegger from the small record label and noise collective Radon disproved the rumors by contacting Mackay and arranging to release his first solo recordings. Radon released the "Death City" single in 1999, and Mackay began to perform and record regularly with a revolving line-up of musicians associated with Radon. The first full-scale tour of Steve Mackay and the Radon Ensemble was mounted in July 2003; with a percussion-heavy lineup that featured bassist Marlon Kasberg (Liquorball), drummer Sam Lohman (Nimrod 36), multi-instrumentalist Travis McAlister (Nequaquam Vacuum), scrap percussionist and vocalist Noah Mickens (also Nequaquam Vacuum), and drummer and band leader Scott Nydegger (Sikhara). Other musicians who have performed and recorded with the Radon Ensemble since then included the multi-instrumentalist Tyler Armstrong, projectionist Ed Cooper, bassist Giovanni Donadini, Nyko Esterle, multi-instrumentalists Kamil Kruta of Koonda Holaa and Dan Kauffman, bassist Jason LaFarge, saxophonist Vinnie Paternostro, Fabrizio Modonese-Polumbo, saxophonist Shane Pringle, Frank Pullen, Suzanne Thorpe (Mercury Rev), John Wiese (Bastard Noise), and drummer Ed Wilcox. Mackay also appeared at live shows by Violent Femmes, with whom he played off and on for over two decades after appearing on their album The Blind Leading the Naked. Radon released the Smegma–Mackay collaboration album 30 Years of Service in 2005, his full-length album Michigan and Arcturus (2006), a vinyl-only release with the Radon Ensemble entitled "Tunnel Diner", and in 2008 Resipiscent released Smegma's Live 2004 featuring Mackay and Jello Biafra. Mackay's solo discography included a self-released collection of solo and group demos from the 1980s called En Voyage, and such compilation albums as Popular Electronic Uzak, You've Got Your Orders 3, and Multiball Magazine Issue 2. The Steve Mackay Ensemble continued to perform live and on radio, and embarked on a tour of the US and Europe in 2006. In December 2007, Mackay recorded two day sessions at the Big Baldy's
