This is a list of heavy metal guitarists from the 1960s to the 2010s.
 Heavy metal guitar players use highly-amplified electric guitar playing that is rooted in the guitar playing styles developed in 1960s-era blues rock and psychedelic rock.
 Metal guitar playing uses a massive sound, characterized by highly amplified distortion, extended guitar solos and overall loudness.
 The electric guitar and the sonic power that it projects through amplification has historically been the key element in heavy metal.
Heavy metal bass is the use of the bass guitar (also called "electric bass") in the rock music genres of heavy metal and hard rock.
 The bassist is part of the rhythm section in a heavy metal band, along with the drummer, rhythm guitarist and, in some bands, a keyboard player.
 The prominent role of the bass is key to the metal sound, and the interplay of bass and distorted electric guitar is a central element of metal.
 The bass guitar provides the low-end sound crucial to making the music "heavy".
 The bass plays a "...more important role in heavy metal than in any other genre of rock."

The Deed Is Done is the sixth studio album by American southern rock band Molly Hatchet, released in 1984.
 This is the first Molly Hatchet album with only two guitarists, after Steve Holland had been replaced by ex-Danny Joe Brown Band keyboard player John Galvin and the return of drummer Bruce Crump.
 The sound of the album is quite different from the southern rock of the band's earlier offerings, completing the transition towards more commercial and FM-friendly hard rock.
 This album was reissued in 2013 under the German label SPV/SteamHammer.
Gator Country was an American Southern rock band formed in Davie, Florida, in 2005 by several ex-members of the Southern rock group Molly Hatchet.
 The band, founded by vocalist Jimmy Farrar, guitarist Duane Roland, drummer Bruce Crump, guitarist Steve Holland, and bassist Riff West took its name from the title of the hit song, "Gator Country".
Black Oak Arkansas is an American Southern rock band named after the band's hometown of Black Oak, Arkansas.
 The band reached the height of its fame in the 1970s with ten charting albums released in that decade.
 Their style is punctuated by multiple guitar players and the raspy voice and on-stage antics of vocalist Jim "Dandy" Mangrum.
Ghost Riders is the sixth album by American southern rock band Outlaws, released in 1980.
 The album was produced by Gary Lyons.
 It is regarded by many fans as the last "Outlaws" album that followed their old fashioned southern rock style, and also a comeback after some mediocre albums saleswise.
 Their cover of "(Ghost) Riders In the Sky" was one of their most successful songs, and has earned the band some attention from outside the southern rock circles.
