Funny that, I grew up in a 'musical family' with a father who played violin (as a hobby) and a mother who was a concert pianist.
Always loved classical and opera, went to lots of concerts in The Hague, Amsterdam, Milan, Vienna and places like that.
Then at 13 / 14 I really got into the blues, cut my first record at 15, and from then on got really into the, then, 'heavy' stuff, and worked with most of them, from the who to led zep and deep purple etc.
In the last decade I also really got into the whole industrial scene, where I found with bands like Skunk Anansie, Fear Factory, Sepultura etc., again some of the passion and emothin which I thought music had lost completely. Now that genre is getting main stream, and despite that, its still awsome with often outstanding lyricks etc (S of a D for instance).
In the meantime, I still love my blues, my metal, my opera, my industrial, my classical.
The key (me thinks) - its art, screaming or not, and art is only art if it has passion and comes from the heart. Doesn't matter what it is, opera or industrial. Likes or not likes is just personal preference, and if its good and moves you, youjustgottaloveit.
