I can see what he means though. If you really like a guitarist you want to be able to listen to an album where it is fairly similar. This way you can sit down and listen to it all the way through and not have to skip songs that are so different and are not for you. This was what i ment when i said about michael angelo being the same. If you have every song of yours sound very different then you will get lots of people liking maybe only 1 or 2 songs that you have written meaning you have a very small number of people that like enough of your songs to buy an ambum of yours or come to see you live.
I'm not saying that satch is like this because i have watched his dvd and if i remember, i liked all of the songs he played. I agree with the fact that its good to change songs a lot and have them sounding very different so they are not all exactly the same and they can all still be very good. Obviously satch didnt go wrong in making his songs so different because i know so many people who like him and he always has that unique style in every song which is what is important.
I hope you see both sides of my arguement.
