It didn’t take long for the Infamous Stringdusters to catch the ear of the bluegrass community. Shortly after releasing their Sugar Hill Records debut album, “Fork in the Road,” in 2007, banjoist Chris Pandolfi, guitarist Andy Falco and company won IBMAs Emerging Artist, album, and song of the year. Steeped in bluegrass and its rocked-up cousin, newgrass, the band pushes the boundaries to create vibrant, progressive music as experimental as it is brilliant. On Saturday, the Stringdusters bring it all to Lincoln Theatre. www.lincolntheatre.com
