The first George Michael collection to feature Wham! songs, TWENTY FIVE celebrates the smooth-voiced British singer's initial quarter-century as a pop performer. Along with presenting a handful of cherry-picked Wham! tunes, including the giddy "Wake Me Up Before You Go-Go" and the 1980s holiday classic "Last Christmas," this two-disc set surveys Michael's solo material, covering some of the same ground as the earlier LADIES & GENTLEMEN compilation, with hits such as the jangly "Faith," the soulful "Father Figure," and "Don't Let the Sun Go Down on Me," a dramatic duet with Elton John. <p>Where TWENTY FIVE differs from LADIES is in its omission of a few key singles, particularly the sensual "I Want Your Sex" and the rambunctious "Monkey," and addition of previously unreleased songs (see the funky, techno-tinged number "An Easier Affair"). Although it isn't comprehensive enough to be considered the definitive George Michael anthology, this 29-track offering succeeds as an intriguing overview of the flamboyant vocalist's '81 to 2006 output.
