Aye man, pretty much. No difference at all apart from the mix and it being an early version without some added extras added soon after. I'm recording the new stuff this year so hopefully that'll be something new to add to the other 7 tracks.
Hey man, you really aren't missing much by not having the demo. It's pretty much the same as the album, just a different, more raw mix, and it doesn't have the added layer of screaming at the start of 'I'. If you really wanted I could email you the files? But it's not a severe loss.
