I'm glad that he slows down the musical pace a little bit and discovers deceleration. He could do the rock thing (he proved it several times in last concerts), but i think it's a better statement to focus on melody, harmony and on the story; in a time where speed is everything and people suffer from stress, burnout and so on.
Of course, speed, dancing and shaking have their effects, but there are so many musicians out there who want to rock a crowd, and only a few dare to slow down and to play in a moderate, melodic way. I like it how he plays nowadays. (and of course i loved the rock thing as well in the past, but for me it doesn't feel apropriate anymore)
