The Oakland, California-based titans of metal might be down to just one original member (founding bassist Adam Duce left the band in 2013, resulting in a lawsuit), but the Machine Head flag still flies high. Last year’s Bloodstone & Diamonds, the band’s first album with new bassist Jared MacEachern, was released through Nuclear Blast, marking the end of their relationship with the iconic Roadrunner Records. Recorded at Green Day’s JingleTown studio in Oakland, Bloodstone & Diamonds — featuring a Manson family-inspired track entitled “Night of Long Knives” — earned the band its highest charting album ever, entering at No. 21 on the Billboard 200.
