Yeah, sorry, late night rambling...! :lol:
I went off on a rant which was nothing to do with Uli Jon Roth and his esoteric approach. That's just a particular way of looking at music which may work for some people if they see things the same way, there's no trickery or clever salesmanship involved, as far as I can see.
But what I did get sidetracked into ranting about (in my usual off-topic manner), you see all these things which seem to offer quick-fix, almost magical solutions to all life's problems. Like weight-loss plans where you don't have to think about what you eat (yeah right). And deep down you know it can't be that simple.
It's like those David L Burge Perfect Pitch courses I've seen advertised in Guitar Player for the last 30-odd years. They used to be cassette tapes, they're probably downloads now...! It sounds great, just imagine having perfect pitch! And it may very well work as an approach but it will NOT be simple, it'll involve many, many hours of work.
