Robert “Throb” Young, the original guitarist for Scottish rock band Primal Scream, was found dead at his home in Sussex on Tuesday. He was 49 years old. A cause of death has yet to be determined, but The Guardian reports that his death is not being treated as suspicious.

Young joined Primal Scream in 1984, though he had gone to King’s Park Secondary School with the band’s founder and singer, Bobby Gillespie. Young was originally tasked with playing bass, but after original guitarist Jim Beattie left the band following the release of the Sonic Flower Groove album, Young switched to guitar.

As a guitarist, Young was a pivotal part of Primal Scream’s run of classic albums in the 1990s, such as Screamadelica and Vanishing Point. He performed on every album the band recorded up until 2006’s Riot City Blues, after which he departed the band for personal reasons.

In a statement, both Gillespie and bandmate Andrew Innes mourned their fallen friend. “We have lost our comrade and brother Robert Young, a beautiful and deeply soulful man,” the two said. “He was an irreplaceable talent, much admired by his peers…He was a true rock ‘n’ roller. He walked the walk. He once said ‘when we go onstage, it’s a war between us and the audience.’ He never let go of that attitude.”

Young is survived by his wife Rachel and his two sons from a previous marriage.
