Excuse me but lumping in any of those death metal bands with Black Sabbath is blasphemy. Ozzie actually sings, he doesn't just scream into a microphone with lyrics that no one can understand. Black Sabbath plays more than one cord of music in their songs. Black Sabbath 4 is one of the greatest hard rock albums in the history of hard rock. Me and my band learned everyone of their songs and played them pretty damn well. Other hard rock bands were Led Zeppelin, Jimi Hendrix Experience, Deep Purple, Uriah Heep,Grand Funk Railroad, too name a few. Death Metal( my son was into that and his band played it in my house) is a form of music that is an affront to real music. Every death metal band sounds the exact same, with the exact same singer screaming into their microphones at the top of their lungs and being totally unintelligible.
Because my parents used to tell me my music was garbage and a total affront to the music they grew up listening to, (Sinatra,Tony Bennet, John Coltrane, Miles Davis, and plenty of others, my parents choices of jazz was something I listened to an appreciated) I gave my son's music the time and consideration that my parents never gave my music. After giving his music every shot I could, I had to determine that his band sucked, his music sucked and the entire genre of death metal, sucked dead donkey dicks.
I really tried to find something of value in it, but no matter how hard I tried, I could do nothing but call it like I saw it, garbaaaaggge. Please do not get upset with me death metal connoisseurs I really really tried to like you. I am a musician( drums and other percussion instruments) so I have a good ear for all kinds of different music. I like old Motown, Jazz, Classical, Reggae, Sinatra, Dean Martin, and other crooners, almost every genre there is, but death metal is beyond my understanding.
