I haven't heard all from Alison Krauss, Gillian Welch, & Steeldrivers. Just a few songs.
I heard mainly Goat Rodeo Sessions, Sarah Jarosz, Sierra Hull, and Wailin' Jennys.
It seems to me like Krauss, Welch, and Steeldrivers are more "Country" than Jarosz, Hull, and Jennys?
Or do you consider them all equally Bluegrass?
