"The Butterfly" ist ein exzellentes Kollaborationsalbum zwischen dem irischen Fiddler Martin Hayes und dem New Yorker Streichquartett Brooklyn Rider, die irische Traditionals neu interpretieren. "The great fiddler Martin Hayes speaks with the soul of a poet. A remarkable artist, the only one of his type." - The Sunday Independent, Ireland. "Brooklyn Rider is really like no other string quartet. Any previous notions you had of string quartet music will get shaken up and ultimately thrown out for good." - Times Union, USA
