The harmonica playing is tops. I really liked the solo on that first video, the guy just mixes it up real well, shifting between ideas he sounds clear and unmuddled. Every note scores. There's nothing that he plays there that sounds like he's stalling or just filling a gap.
That's a sharp band overall. They aren't covering a lot of new ground in those videos, but as tight and well studied as they are, they all deserve a lot of credit.
Anyone who thinks that a harp player is just half a musician, or that harp playing should just be a sideline for the vocalist should check out that first video especially. Gonzalo is a snap fit for that band and if anything had happened to him before the show there would have been a big empty hole to fill. He's sounding pro all the way.
