Bluegrass 45, from Kobe, Japan was one of the most prolific bluegrass bands in the 1960s. Fifty years later, they reunite to retrace their 1971 tour deep in the American South. With infectious joy and humor, CALLED TO THE MOUNTAINS explores their unique musical world, as we get to know the individuals who make up the band and their connection to the music and culture that called them, accepted them, and forever changed their identities––from 5,000 miles away.
