Fifty years of Amnesty International are marked with this colossal, four-CD compilation of Bob Dylan covers – 75 tracks from as many artists, ranging from the trad (Pete Townshend's "Corrina, Corrina", the upbeat old-time of Carolina Chocolate Drops' "Political World") to the rad (Sussan Deyhim's "All I Really Want to Do", Ke$ha's pleasingly pared "Don't Think Twice…"). Elvis Costello harmonises with himself on a dubby "Licence to Kill"; fans of Adele will like her typically intense piano-backed live version of "Make You Feel My Love".
