Plovdiv will host the free concert of the American band "Tumbling bones". The event will take place on 14.11.2014 at the City Hall of Culture "Boris Hristov". Tumbling Bones is an ensemble of young men inspired by old music. Drawing on bluegrass, pre-war folk, and a bit of the contemporary rock ‘n’ roll the guys were reared on, they make their music with nothing but acoustic instruments, tap-shoes, and—most of all—their voices.
