If this is talking about worst albums from a favorite band, back when I was 15-16 I was into Black Sabbath with Tony Martin vocals (dunno if thats even really classified as metal, it sounds more rock-ish) the girls will probably like his voice, its gorgeous, anyway, Their greatest album was Tyr, Headless Cross not too bad, Cross Purposes not bad either really.. but then.. they brought out Forbidden.. omg.. that was the end of my fetish, its pure shite.
Now, I gotta say worst album for a band I love.. sorry to say, is SyX's self titled debut. I cannot listen to it, Rods vocals are simply awful and the lyrics and chorus' are cheesy.
Theres plenty of other bad albums, but I generally find myself unable to like the band at all after hearing them.
And I just heard Francesco Fareri's slow guitar solo. I wouldnt say he is really THE worlds worst guitarist, but I did truly find his music extremely boring and unimaginative and lacking variance. I think perhaps he should stick to letting other people write the music.. I might listen to a bit more than just that though to form a sound opinion.
