When Magnum released 2018's Lost on the Road to Eternity, keyboardist Rick Benton replaced Mark Stanway, who'd quit (for the third time) in the middle of a tour. The album's razor-edged, riff-laden hard rock sound contrasted with the plodding bombast and balladry of 2016's Sacred Blood "Divine" Lies that, frankly, sounded tired. Longtime drummer Harry James left in 2017 and was replaced by Lee Morris. The resulting tour was wonderfully documented on 2018's surprising On the Road to Eternity live outing. Finally, in June of 2019, Al Barrow, the band's bassist since 2001, retired from music. American Dennis Ward claimed the spot just before Magnum entered the studio to record The Serpent Rings. Founding members guitarist Tony Clarkin and singer Bob Catley are the only remnants from the 20th century. As evidenced on their 21st studio album, the personnel changes stoked the fire in the bellies of these two mainstays.
