A few bands ago, in a trio-plus-vocalist, I was teamed with a very good drummer who was also very inventive. We did "Sultans of Swing" - the original, of course, has keys and a second guitar as well as the lead guitar. After we'd rehearsed it a few times, rather than upping things when the first solo came round, the drummer dropped back. I realised what he was doing and followed him, so we were really underplaying below the first solo which suddenly didn't sound empty. The second solo got full tilt boogie which worked well, but probably wouldn't have without that alternative dynamic on the first one. It wouldn't work on a guitar solo using searing distortion, but fitted nicely with the slightly overdriven Knofler tone.
