Its strange,if I push any harder than that to make a technical riff,it usually ends up sounding contrived,or "just for the sake" being tricky or flashy.I find just playing what I want lets that more melodic bit of riff out and speaks from me instead of being just notes.
I listen to alot of death and black metal,but have trying to lighten up a bit,to a more radio friendly sound.I'm obviously not there yet,but my next tune should be radio friendly...even if its a college campus.
edit:oh yeah here is the URL to my myspace,contact me on there if you wanted to put something together down the road.
