I saw them live in 2008 at Rock am Ring-Festival in Germany, 2009 at Big Four and 2012 at Rock am Ring!
Both times they were brilliant, but I realised that James had some Problems with Songs from Death Magnetic! To be honest "That was Just Your Life" is a really heavy Song and the Riff is very hard to play... You need a lot of practice! I never understood, how James could sing at the same time playing this Riff!
