New Gloucester-based Bald Hill is known throughout South/Central Maine for its unique brand of blues-inflected newgrass, folk rock, traditional country and Americana. Formed in 2015, the band’s core collaborators (and their predilection for classic bluegrass) go back another decade. The intervening years meant evolution, fashioned by additional voices and varied instrumentations. But the band’s sound and tastes have remained subtly antique, thoroughly eclectic, and best performed around a single, central mic. Today Bald Hill performs original tunes alongside traditional/bluegrass standards, while paying equal homage to, among others, the neo-Appalachian songwriting of Gillian Welch and Dave Rawlings, the vintage country of Johnny Cash, Loretta Lynn, Jimmy Martin and Hank Williams, the bluesy folk of Richard Thompson and Lucinda Williams, the alt country of Son Volt and Wilco, and the classic rock of The Band, Neil Young and The Grateful Dead.
