I'm sure Mikes just saying theres no concept just so we can figure it out ourselves. I mean on 'The Baying of the Hounds' Mike sings "Beneath the Mire...', I had to check we were still on track 2 when he sang that. Its clearly a reference to track 3. Even if there is no overall concept theres probabaly one between a few songs. I sure the concept is just about a guy how gets posessed by demons or satan or something...hmmm.....I dunno....any thoughts?
