Unfortunately, due to the way DCD recorded, multi-tracks only exist of the first album and ep (and yes, Brendan's looked at remixing them but the sounds he disliked were in the recording so he couldn't do anything satisfactory with them). We did want to do surround mixes but without multis there's nothing that can be done. Many of the albums were actually created in the final mastering where triggered samples (not on the multitrack) were mixed in live. This means that, apart from the stereo masters, there is no other recording containing all the musical elements.
