If you get sad and alcoholic listening to blues, the blues is played right!

You are making a compliment
The guy in the
OP has stellar technique for fingertapping and harmonics (those bell-like notes). I do think he has an effect pedal helping him with the sustain and volume (a sustainer) or he hammers-on really, really, really hard, for tapped notes on an acoustic guitar don't have a lot of volume and sustain by themselves.
