Debuting at #6 in its first week on the charts, Older by George Michael was his attempt at more mature music (hence the name of the album). According to the Wikipedia page, the album was very successful in the UK and Europe, but less so in the United States.
Personally, I have no use for a more mature George Michael. His catalog of pop music with Wham! is all I really want or need from him. Wake Me Up Before You Go-Go, Careless Whisper, and Last Christmas (at the right time of the year) are some of the best pop songs ever made. His first solo album Faith is also excellent because he didn't try to get away from his pop roots. Older is trying too hard, and that's not what I want from George Michael.
My recommendation is to skip this album but definitely check out his earlier work.
