I can attest that sometimes more is better.
Ive shared in another thread where I have been going thru all sorts of video tapes of my band and there are times where I have approached solos like Sean does in his videos, I mean what the hell am I thinking, how many notes can I play or what? Or damn my hands are fast?
But then I find a song where I really milked each note for all its worth and those solos stand out in my mind way more than the shredder type, I mean there is nothing wrong with a burst or two, but 32 bars of shredd gets on my nerves and I lose interest for some reason, and Im a fughen guitar player.
Take a player like Randy Rhoads and the Crazy Train solo, sure Randy shreds as well as anyone, but in that solo he burst then he relaxes, gives some space in there or breathing room, then burst again, it comes across as tasteful, instead of just showing off.
Eddie Van Halen, the same thing, even on Eruption, there are pauses and breaks that draw you in more, thats why its one of those iconic guitar solos, if he had just played ever note as fast as he could I dont think that solo would have stood the test of time that it has.
So just because a old blues player said what he said doesnt mean its not relevant to other genres. Im as guilty as anyone on this site of overplaying at times.
