Huh? SLS has worked wonderfully for millions of people. With SLS, one can gain an octave within a few short lessons, as opposed to classical, where for some gets them nowhere. Ask anybody who has trained in SLS, and they'll tell you.
I'm not saying classical is bad; if it works for some, awesome. But, if what one wants is a higher range, and fast, SLS is a much better way to go. It's worked wonders for me.

"Don't let them mold your mind, they want to control mankind, seems like their only intention is to exploit the earth; and you trust in their deceit, your mind causes your defeat, and so you become an invention to distort this earth; propoganda and lies, is a plague in our lives, how much more victimized, before we realize (hey) ... they'll make it attractive, to get man destracted, corrupting your (soul), polluting your (soul), destroying (your soul, mind control) ... ooh grand master, let the people go, you put them in total confusion, to downs-troy their soul; for they practise what you preach, so they're always in your reach, hi-tech slavery in these days, its mind control"
