For me the title 'Ghost of Perdition' first evoked the idea of a massive, chugging, sort of slow but incredibly heavy song that was mostly dependent on a few main riffs...not this amazingly agile piece we have here with so many highlights. I like this better.
Oh and I heard a bit of Orchid/MR in the riff @ around 1:20
