Being from KY, we get our fair share of Bluegrass music. The town I live in now is home to the Bluegrass Hall of Fame Museum, and we have one of the largest annual Bluegrass festivals around (ROMP in Owensboro, KY). I grew up in the town where Sam Bush is from, and also a couple of the other New Grass Revival members - Bowling Green, KY - home of the Corvette (I gave tours at the Corvette Plant for 3 years while I was in college), and it’s only about 1 hour north of Nashville, TN, so I grew up on country music.
Tyler Childers is great. His early stuff was a little too sad/whiny for me, but his new album is great. I saw him perform with John Prine at a local outdoor venue in a podunk town here in KY about 3 years ago like 15 miles from where Prine’s song “Paradise” is based off of.
Chris Stapleton and Sturgill Simpson are also from KY (the Lexington area), so they’ve been pretty popular around here.... Trampled by Turtles is about as good of any modern bluegrass you’ll find.
