Although I don't have a Chaos warband (yet!) and so no eternally damned champion who's entrance on battle needs a suitably grandiose fanfare here's my choice anyway - which actually fits quite well with my contribution to the Oldhammer Day - hordes of Orcs bearing down on the doomed village of Orc's Drift -more of which shortly.
Were I to chose an Iron Maiden track (good choice of band Erny!) it'd have to be this...
However, Maiden's been done and I'm not big on the whole Thrash metal thing.
So how about a bit of British Blues/Prog Rock in the form of the Groundhogs -
