If I were you I'd try and find a voice coach. SLS is THE BOMB fo real. You can find one at speechlevelsinging.com. I'd say a level 4 or 5 will be your best bet, they're going to have a lot more knowledge as they've been doing it a lot longer. I love my voice coach more than I can say, honestly she's incredible and I feel so blessed to have found her. Also, the Brett Manning stuff is great. If you can get his DVDs do that for sure. I'm planning on going to Nashville next year on spring break to do one of the artist development weeks with him, I just have to get it all figured out!
