I'm starting on a two week layoff to try to finally get rid of the persistent hoarseness that led my ENT to tell me he'd like me to get a second opinion. So, I'm going to be doing things to improve my overall musical abilities such as playing guitar and educating myself on how to out a home recording studio together. I've never used a DAW, but I just bought a computer that has Logic Pro installed in it as well as Final Cut for video. I expect there's gonna be quite a learning curve on these things like learning to use a DAW and learning to make videos! None of it will be as challenging as avoiding the temptation to sing, but I'm so tired of not having a clear voice that it should give me an incentive to stay with this two week rest period. There are still a couple places in the Extreme Singing course I hadn't seen yet. I just watched "Head Voice Edging Grit. As soon as I first heard your example, my first thoughts were: "Oh, Axl Rose's technique...or Rob Halford's technique"! Speaking of extreme singing, it occurred to me that one of the great pioneers of raw, gritty singing was Janis Joplin, but she seems to rarely get talked about in those terms because she wasn't a heavy metal vocalist. Her music wasn't even hard rock, but her vocals were more extreme in the late 60s than what Plant or Marriott were doing. Sabbath started heavy metal but Ozzy Osbourne wasn't an extreme vocalist. Janis Joplin's influence would go on to be felt for decades. Her vocals were intense by any standards!
