Metal Heart is the sixth studio album by German heavy metal band Accept, released in 1985. Although the group had recorded before at Dierks-Studios, this was the first album produced by Dieter Dierks himself. It marked the return of guitarist Jörg Fischer after a two year absence, with Herman Frank having been his replacement. This album was a cautious attempt to crack the lucrative American market with more accessible songcraft and emphasis on hooks and melodies. Although critically panned at the time, today Metal Heart is often considered by fans as one of the band's best records. It contains several of their classic songs such as "Metal Heart" and "Living for Tonite". The band also makes a detour into jazz metal territory with the unusual song "Teach Us to Survive".

Accept is a German heavy metal band from Solingen, formed in 1976 by guitarist Wolf Hoffmann, singer Udo Dirkschneider and bassist Peter Baltes. Their beginnings can be traced back to the late 1960s, when the band got its start under the name Band X. Their current lineup consists of Hoffmann, vocalist Mark Tornillo, guitarists Uwe Lulis and Philip Shouse, drummer Christopher Williams and bassist Martin Motnik. Accept has undergone numerous lineup changes; Hoffmann is the last remaining original member, and the only band member to appear on each album. As of 2024, the band has released seventeen studio albums, five live albums and nine compilation albums.
