Jason has been hangin w/ the Yonder Boys quite a bit lately. I'm not sure, but I think they may have gotten to know each other through DelFest...the meshing of the traditionalists with the hippies.
Jason played all Yonder sets for four days in Tulum last December, and quite a few other sets there, and he was also with Yonder during during the Charlottesville and Asheville shows this February...and yes, he adds a lot to their sound. Killer version of "Come Together" in Charlottesville and Jason tore it up.
I hope to see Jason in Telluride with those mountain boys.
