I liked their rockabilly/hayseed music more than some of their more experimental ponderings. Still get a kick out of Tennessee Jed now and again.
Jerry Garcia always thought of himself as first and foremost a bluegrass musician, and only secondarily as a stoner rock and roll musician.
I’m not sure where the neckties come in to it, but I like them too, and I have a bunch.
You'd probably like these two. Check out New Riders of the Purple Sage and Blueground Undergrass......
