I'm With Her described themselves as "Bluegrass Adjacent"
Speaking of awesome shows, a few weeks ago we saw "American Acoustic" featuring the Punch Brothers, Watchouse (formerly Mandolin Orange), and Sarah Jarosz at the Mountain Winery in Saratoga , freekin' awesome show. NOT bluegrass, just adjacent
and Tuesday, we saw Robert Plant with Allison Krauss in Napa. another awesome show. Definitely NOT bluegrass (even though Allison has plenty of BG credentials, with her Union Station ).
