- Their name implies that they are actually the opposite of a bluegrass band (“Green Sky” vs “Blue Grass”). “We play acoustic instruments but we put on a rock’n’roll show. We play in bigger clubs and theaters, there’s a killer light show, and we’re as loud as your favorite rock band. It’s not easy to make five acoustic instruments sound like this but it’s something we’ve spent years working on.
