Keller Williams does a little drumming on his guitar as well as some interesting strum patterns, although the things he does with his mouth are the main attraction. To clarify for the benefit of certain people who may be imagining all sorts of things one can do with one's mouth, he imitates the sounds of a shaker, a ride cymble, an upright bass, and a TRUMPET! Really, like if you closed your eyes you could believe there's a trumpet player next to him. That coupled by the dynamic playing and the drumming that includes playind open-hnanded on the side of his guitar with his wedding ring (CRAACKK!)makes hims ound like a whole band! Just thought I'd mention him.

And by the way, I thnik calling a guitar a "bodhrán with strings" is giving a lot of credit to the guitar. :-) LOL

Slán agat,
