REM, I think all of their early stuff was exceptional. One of my alltime favourite albums ever is 'A Song For All Seasons' which quite a few Renaissance fans don't like.
A few years back I bought the album 'The Other Woman' with a different singer and also bought an Annie Haslam solo CD. I have to say that the Annie Haslam CD was the poorest of the two. Maybe she's just gone off a bit with age.
Looking back on the earlier Renaissance stuff though it's amazing to see the quality of guest musicians that appeared on their albums.
