That's a great technique when you're being a fairly rough spoken character, however, I will say that between your regular voice, and your vocal fry, there is always a give and take, you sacrifice a bit of tone and a bit of range in order to have this secondary range, so, as a Metal singer, myself (not Death, mind you, Power), I'd recommend really considering the risks when exploring vocal fry. There's a reason singers like Jari Maenpaa and the guy from Killswitch Engage are famous, they're truly lucky to have maintained a good tone (however in Jari's case, he does not match the tone and power of pure singers like Timo Kotipelto and Hansi Kursch), so vocal fry is definitely the way to go if you want to voice the extremely low characters, however, if you just want to go a bit lower, I'd recommend using yawn space, which you may or may not have heard of, it is an operatic way of breathing that provides that rich tone synonymous with Opera singers. What I'd just say about any more contemporary technique is just know the risks, growls don't last forever, so it's all about what you'll sacrifice, I'll always recommend Opera as it is a style widely taught by professionals, and it is easily the safest way of using your voice ^__^





Although, I don't really want to change my natural tone of voice (I'm not a metal singer, a pop singer maybe?).. And growl is a technique that doesn't come easily to me, and strains my voice too much (after which I get worried and stop singing altogether.. O_O) It's too much of a risk for me..
