A hugely influential West Coast heavy metal quartet, Machine Head's neck-snapping riffs and earth-shaking grooves helped shape the New Wave of American Heavy Metal movement of the early mid-'90s. The band's aggressive and wide-ranging style, which combines elements of thrash, groove, and nu-metal, has yielded seminal contemporary metal efforts like Burn My Eyes (1994), The Burning Red (1999), Through the Ashes of Empires (2003), and The Blackening (2007). Led by vocalist, guitarist, and sole constant member Robb Flynn, Machine Head released their tenth studio long-player Of Kingdom and Crown in 2022.
