Confidence, Pure Confidence……
Slash has put in the years it takes to get the level he’s at. He is also secure that whatever he plays well, as a lead the fans will like. He does not look like he second guessed anything he played in the 2:20 to 4:20 area. Watching it with no sound I did see different patterns played over, then strung together in many different ways.
You just need a little bigger fan base.
