Between 1998 and 2006 Shields became a frequent collaborator and semi-permanent touring member of Primal Scream. He contributed guitar, produced and mixed tracks on two of the band's studio albums: "XTRMNTR" (2000), and "Evil Heat" (2002). Primal Scream frontman Bobby Gillespie has said that " brings something that nobody else in the world can bring. He plays guitar the way that nobody else in the world plays guitar," adding that Primal Scream considered Shields to be "part of the family, very much so." Shields has remained close to the band following his departure in 2006, remastering Primal Scream's third studio album "Screamadelica" (1991) in 2010 and contributing guitar to "2013", the lead single from "More Light" (2013). Gillespie has since commented on Shields' absence, noting that "there's always room for Kevin Shields—always."
