A group with one foot in acoustic music traditions and another in the more adventurous side of roots music, the Gibson Brothers blend the close harmonies and agile picking of bluegrass with a melodic approach that incorporates elements of contemporary country and classic rock. A rare example of a successful bluegrass act based on the East Coast, they showed off their mastery of traditional bluegrass styles on 1997's Spread Your Wings and a more progressive approach and adventurous choices in material on 2006's Red Letter Day. With 2019's Mockingbird, produced in part by Dan Auerbach of the Black Keys, they moved past the strict confines of bluegrass into a fuller sound informed by country, R&B, and Southern rock more than acoustic music, while 2023's Darkest Hour saw them embracing both traditional bluegrass and rock-oriented arrangements.
