Red Allen was a fine guitar picker, but it was as a vocalist that he made his mark on bluegrass. In 1956, Allen joined the bluegrass band the Osborne Brothers and, with his high tenor lead vocals and the wailing harmonies of the Osbornes behind him, they established a signature sound like none other in the bluegrass scene at that time. His lead tenor vocal style became the template for every bluegrass band that followed. He later made recordings under his own name and was part of the seminal groups the Kentuckians, the Kentucky Mountain Boys, and Red Allen and the Allen Brothers. Allen died in 1993.
