Interesting. it's strange that they've even bothered changing it really- although the mixing/recording was horrendous for the first couple of songs, so i could understand them wanting to sort that out. Have they done this?
It sounds like they sorted it out by just making it louder in places. I'll be honest the raw live mix, definitely covered up things that are not presented well in the new format (guitars and vocals).
I would love to hear someone else's opinion who heard these recent Apollo replays yesterday and today.
Edit... it just started again right now at 4:10PM EST
