Funny that you should mention Joel Guzman. Back in late June, He played at the Smithsonian Folk Festival as did Ed Poullard. They had these discussion presentations; and for one of them this lady interviewed Joel, Ed, and one othe person whose name I can't remember - he was also from San Antonio. Anyway, the interviewer asked them to play a tune together. Now if Ed had wanted to, he could have totally overpowered them with Lawrence Ardoin's diatonic accordion; but of course he did not. But it was real neat to hear this "accordion trio" playing together - one of the things you will not forget.
Ed , ( who is one of the braves here ).. plays triple row as well .. and Joel plays most anything ( diatonic, chromatic, keyboard.. he studied jazz comp in college )..Joel also does asides into blues, cajun, bluegrass and Irish music in his repertoire.. he makes it all look very very easy.. but is the product of being a musical prodigy and 40 yrs of playing/recording in public..
I am sure they have a few songs in common somewhere.. : )
My friend Charles Thibodeaux also played the Smithsonian and some other friends Marlon McAllister and Beth Coffey did Cajun dance demostrations. Austin has a big music presence.
