Drummers have been and shall remain officially excommunicated in most bluegrass bands, festivals, and albums. The snare is the mandolinist’s job and the kick is the bassist’s responsibility.
Bassists however are frequently given solo time but not enough recognition. Some names that stand out are Jeff Picker, Scott Mulvahill, Daniel Kelley, Jimmy Meyer, Geoff Saunders, Ethan Jodziewics, Kyser George, and Becky Buller. There’s so many more that I missed, but off the top of my head those ones are great. My favorite of those is Ethan, he’s just awesome
