I'm with you on that one as 'Raw Power' is one of my favourite albums of all time. The accepted reason for its poor quality for a long time was that the rhythm section tracks had been bounced down and were therefore all Bowie had to work with when he did the original mix. Obviously Iggy's 1997 mix blew that fact out of the water but that remix is such an utter piece of garbage that its unlistenable.
'Raw Power' really deserves to be remixed by someone competent. So do the pre 'Raw Power' demos of all the great tracks that Main Man rejected ('I Got A Right' 'Scene Of The Crime' etc) although, as demos, the chances of those multitracks existing would be slight, I would suspect. Mind you, even in their current state they still sound better than anything on any version of 'Raw Power'.
