If you stick around for the last lick, the annoying part is how bored he looks while he tears that up.
One of the typical "country" guitar (I use the term because it is the typical musical style of these players, it's not to pigeonhole them as guitarists) conventions is a clean tone, and it's really hard to hide sloppiness when you play primarily clean or only slightly overdriven tones.
Love Greg Koch, and Tommy Emmanuel is a primary influence on me although I think he's got a wider array of genres that he dips into (not discounting the importance of Chet, Merle Travis, etc. on his playing).
Check out Brad's "Play" record.
It's mostly instrumental with some vocals here and there. The intent was to feature his guitar more than his voice.
Urban is on that record too on at least one song. Really a cool way to have some Paisley in your record collection if country radio hits aren't your thing.
