The "You Ain't The First" demo sounds like when they tried to mix the album in "Q Sound" which was, if I remember correctly, some new way of mixing music. Even the old Street Fighter 2 arcade cabinets had it. This was on the Alan Niven DAT tapes he gave to a fan to rip and share.
It blows my mind that it was 10 years ago that Alan Niven allowed that stuff to be out!
Originally it was the instrumentals and alt version of 14 years. Then they had the q sound mixes that they were experimenting with. They sounded pretty terrible.
