Although not exactly comparable, I think this is a better idea and much prefer this to Metallica's own S&M, which was a good idea but in practice sounded like a sloppy metal band battling it out with a symphonic orchestra without any interesting results. On this debut release by APOCALYPTICA they simply play classic Metallica songs on 4 cellos. All is performed amazingly well.
The entire album is instrumental and there is no percussion so in effect it is one cello each covering the vocals, two guitars and bass of the original songs. All cellos are acoustic and nothing here is amplified so i'm not sure if this really counts as metal but it certainly has the intensity.
I wouldn't want to hear several albums of this sort of thing but this one has kept me interested for quite some time now. All of the song choices are good but I lean toward the ones of the albums I like best from Metallica of the 80s. Wisely the group decided to add percussion and write their own material after the success of this album.
