Chapman Cultural Center presents The Grascals October 13. The group’s cutting-edge modern bluegrass is delivered with a deep knowledge of, and admiration for, the work of the music’s founding fathers. Timely yet timeless, The Grascals make music that is entirely relevant to the here and now, yet immersed in traditional values of soul and musicianship. Non-bluegrass listeners enjoy a new take on a familiar song, while diehard bluegrass audiences who may have never heard a particular classic, respond in-kind, not even realizing that the song has been Grascalized. Tickets $30.
