Tunnel Vision
IS my favourite track off Blue, but then again I love Ignition to bits as well...
And I definately wouldn't say that Sinner is a BigBeat track, mainly because the bass beat, no matter how "big", is your thumpy all four to the floor, housey type, instead of a more oomph-breaksy one. Amazing track nevertheless.
I like to think of the categories and genres the way Ishkur puts them (here's the link again:
http://www.ishkur.com ), even though his guide isn't completely accurate... And if you look up Hard House there, The Sinner most certainly isn't that either. I'd call it Progressive House, like I call every song with a house beat that is more complex than other house and that I can't fit into any other genre...

(I've been known to mix-up hard house with progressive house in my recent posts too, so don't mind them)
Then again Orbital's music is usually pretty damn hard to categorize overall, which for me is just a good thing.
