I had posted a thread on combining scales earlier, but I need more in-depth descriptions of exactly how to combine scales and what scales combined together sound good. From the name, combing scales, I figured that you just put two scales together (like the major and pentatonic scales). I have found that this sometimes doesnt sound very good, and I would like to know what methods there are to combine scales.
Just from my musical experience, I have found that Randy Rhoads does this alot. If there are any other greats that do this (which Im sure they are many) mention them and I'll check em out. Thanks.
