Unless you are familiar with the NWOBHM (New Wave Of British Heavy Metal) movement in the late 1970s and early 1980s, then you probably have no clue about the band Sweet Savage.
Well, let me just get this out in the open and say that it’s quite obvious (to me) that Metallica frontman James Hetfield tried as hard as possible to mirror the vocal styling of Sweet Savage frontman Ray Haller (at least in the beginning). Metallica also covered the Sweet Savage song ‘Killing Time’ as a b-side to “The Unforgiven” single.
Listen to this track from Sweet Savage called ‘Eye Of The Storm’ that appeared on the NWOBHM ’79 Revisited Double CD compilation that was co-curated by Metallica drummer Lars Ulrich. If you weren’t told otherwise, you’d probably think it was early Metallica.
Side note: Sweet Savage also featured guitarist Vivian Campbell (Dio, Def Leppard) until 1983.
