Seems funny to me that I've never really wondered that there are so few Black musicians in the Bluegrass genre. Tray Wellington is an ETSU alum with a degree from the Bluegrass, Old-Time, and Country Music program. Here's the Tray Wellington Band doing Hartford's Lawn.
Banjo: Tray Wellington; Guitar: Drew Matulich; Mandolin: Thomas Cassell; Bass: Zach Smith
The Often Herd from Northumberland, England doing Sycamore Gap. According to the band, "Sycamore Gap is a dramatic feature of the Northumberland National Park's landscape, situated just to the right of Milecastle 39 along Hadrian's Wall. The tune was inspired by a windy visit to this evocative landmark in the winter of 2019."
