APOCALYPTICA are thrilled to announce the fourth and final exciting single from Apocalyptica Plays Metallica, Vol. 2 – the hotly-anticipated sequel to their legendary debut record. ‘The Call of Ktulu’ follows on from a rapturous response to the preceding three singles: stunning reinterpretations of ‘The Four Horsemen’, ‘The Unforgiven II’ and ‘One’. Most notably, ‘The Call of Ktulu’ features a truly remarkable guest: legendary Metallica bassist, Cliff Burton himself.
