maddix was ok, he was certainly solid - but he came from a very different musical background and didn't really fit.
kick reni out and announce the fact with the explanation that he stopped the band moving forward creatively. it wouldn't noticeably affect ticket sales. obviously the band, management/promoter don't want to rock the boat and keep the big gigs coming though and this will continue. i'd be amazed if the upcoming gigs are the last.
The band and promoters/management will do everything in their power to keep Reni sweet, which is kinda sad as he's pretty much untouchable doing that, hence not playing on new recordings, missing rehearsals.
If they continue after Glasgow, I'll be completely stunned.
