I attended the OMG tour in the o2 arena in February, and loved every minute of every song (a full set of 19 songs, mixing the new from his album Raymond v Raymond with some old classics, including a special tribute!).
I'm a huge Usher fan and this DVD encapsulates the atmosphere and quality of the show perfectly, a must buy for all fans.
Extras include a 'making of the tour' backstage feature.
Not to be missed regardless of whether or not you were lucky enough to experience the real thing...excellent.
