This weekend, I pulled out the Les Paul, put Wings Over America on the player, and started to play along.
It gave me a new appreciation for the way Paul McCartney arranged his songs. I played along with the first album side, the rocky bits, and realized that the rhythm guitar plays very sparingly. At first, I was playing power chords and fills, but it was too much. So by the second song, I backed off from playing "too many notes" and played economically.
That reinforced what I already new. I always tried to impress this upon my last band, but everybody went full-force 99% of the time and had no sense of dynamics. If my new band takes off, I'm going to make sure that the players appreciate this point. Sometimes, as we know, less is more.
