28th Annual Targhee Bluegrass Festival August 7-9, 2015 Started in 1987 Targhee Bluegrass is the Grand Daddy of Bluegrass Festivals in the Northern Rockies, combing great Bluegrass with the ultimate mountain lifestyle. Grand Targhee Resort's Bluegrass Festival has been a mainstay for Bluegrass aficionados for over two generations with stage appearances by artists and performers during that span that all Bluegrass Festivals envy. During the week leading up to the festival, many of the stage performers and artists play host to a very unique camp and music teaching experience by attending the Targhee Music Camp.
