Wow...
My want to write this symphonic metal concept album stemmed from the Epica and Black Halo albums. And my voice is practically modelled on Roy Khan which is probably why you think I sound like them.
Yes, I do know Kamelot. Quite well. Although I'm not terribly keen on their newer stuff. Tommy is a fantastic Vocalist and is ridiculously sensational for Seventh Wonder but there's something 'dark' that I love about the Roy Khan Kamelot, they seem more mainstream now.
I'm sill on Logic. I was taught how to use it through school so i know it extremely well and find it great for practically anything. But as you can tell with the demo, it sounds.... Ok, with their standard libraries but not in any way a profesional standard quality. When my laptop bust, I invested in an Imac, still running Logic but ploughed more resources into Kontact and better sound libraries from Native Instrumetns, Heavyocity, SoundIron etc, ect. Next step would be probably to get some effects on board. I find some of Logics VSTs such as the reverbs and compressors, limiters, etc, to be a bit limited in their capabilities. (perhaps I just suck at creating reverb)
