Whatever your views on George Michael might be, he has, to my mind, produced some excellent solo work over the years.
Listen Without Prejudice (Vol 1) (1990) for example, is absolutely cracking. His second post-Wham! album was a commercial flop at the time of release. I don't have Faith, his first solo album, but I gather this was fairly Wham!-like, and people were expecting more of the same thereafter. Listen is GM with his serious hat on, working very hard to demonstrate his songwriting and vocal skills. And doing so very nicely, thank you. All the tracks on the album are highly engaging, with power, depth, and variety.
His third solo album, Older (1998) is similarly serious, leaning more towards the jazz/R&B side of things. This is also very listenable to – sultry and relaxed.
Finally, I also have Songs From the Last Century (1999). This is an album of covers, including classics such as Brother Can You Spare Me A Dime, I Remember You and Miss Sarajevo. All the tracks are excellent, but top of the list is GM's breathy rendition of Roxanne – possibly better than the original (and I'm a big fan of The Police).
There's some real quality here – possibly overlooked because of other things. Unfairly so, if that's the case.
