I have SiriusXM and listen to Bluegrass channel 62 all the time. To me it is the trade for real country music. If you ever have the chance to see Rhonda Vincent in person then do so. I love Bluegrass.
I do occasionally still listen to Bluegrass on Sirius XM. I like RV, but have never seen her live.
The Seldom Scene introduced me to bluegrass almost 40 years ago. I still have a nice handwritten reply from Mike Auldridge to a letter I wrote asking him about the instructional tapes he used to sell.
