Sam Bush was barely old enough to shave when he joined now-legendary Bluegrass Alliance as mandolin player and began to redefine the music of Bill Monroe for his generation. Combining a love for bluegrass with elements of rock, folk and jazz, he co-founded New Grass Revival in 1971, fashioning the genre known as “newgrass music.” A master musician, Bush has served with Emmylou Harris’ band and enjoyed a successful career on his own, releasing seven critically acclaimed solo albums. On Saturday, the Grammy winner will perform songs from throughout his career, including some from his latest CD, “Circles Around Me,” when he brings his band to the ArtsCenter in Carrboro. www.artscenterlive.org
