Metallica

Metallica is a thrash band who led the rise of the genre in the nineties. Originally a speed metal band in the style of Motörhead, they later adopted a more aggressive style that pushed out the party style led by bands like Kiss that had been dominating metal since the seventies. This was also an element in a shift in music from fun to cynical, including the grunge craze led by Nirvana. Metallica is considered the definitive thrash band, with many successful albums. Their hit Enter Sandman is considered by some to be more of a "groove metal" style than a thrash metal style.
