Metal Hammer’s annual Defenders of the Faith tour is usually a bloody good excuse to catch a whole crop of excellent bands all in one place – this year’s line-up was particularly impressive, with headliners Amon Amarth being backed up by the likes of Carcass, Hell, and Bleed From Within. We got our principal photographer, Mr Gary Wolstenholme, to head on down to Manchester to catch one of the last big metal tours of 2013 do its dirty business all over the O2 Academy.
