I like bluegrass but have always preferred old-time central Appalachian music to straight out bluegrass. I like early Bill Monroe more than I like later Bill Monroe and generally prefer the Stanley Brothers and Ralph Stanley to mid and latter Bill Monroe. Simply a matter of personal taste tinged by my own roots.

That being said, The Country Gentlemen was a fine bluegrass group, as were the Seldom Scene, another DC area bluegrass group who hit the 'big time' in terms of bluegrass music, and really enjoyed listening to the link you provided. Thanks.
