"BBC Radio 3 takes up residence at Hull Truck Theatre from 6-8 April for Uproot a three-day festival of live concerts and special Radio 3 broadcasts celebrating the area's folk and roots heritage, as well as its international cultural connections as part of the BBC's contribution to Hull UK City of Culture 2017."
