The Loop - Mimicking Birds

The other versions have been pretty close but I'm almost certain this is the 
correct way to play it, it seems to be the version that Nate Lacy plays and it sounds right.

Low E is tuned down to a B
D is also tuned down to a B 
G is tuned down one semi tone to a Gb

/ - slide
p - pull off
