Well I was thinking about writing this for a long time.
Im a metal head . I used to listen to metal right from school,
and been playin the guitar from around the same time .
The first album I listened to was when I was in school . Chaos AD -Sepultura
I got hooked instantly:-)
I listen to a range of music .from
Beatles to Behemoth
Sinead O Connor to Sepultura
Mozart to Metallica
CCR to Children of Bodom
You can never compare one band to another of diff genres.its a sin:-)
Here is my list in no particular order .
Of course it a matter of personal opinion here, always debatable:-)
