Sting has indicated he regrets Police's reunion tour, calling it "an exercise in nostalgia."
Sting said that he would not have taken part in the global reunion tour in 2007 and 2008 if he had known how he was going to feel at the end.
"At the time I labelled the tour an exercise in nostalgia," Sting told Reader's Digest. "That was simply how I felt and is still how I feel today. I think it's OK to be honest about your feelings and that was the way it went for me."
He added, "That's not a slight on the people I was with or the way things panned out, it's just how I saw it by the end, and let's be honest, that's not how I wanted to remember it. If I thought that would be the emotion I'd be leaving with, I wouldn't have done it in the first place."
Police's reunion tour, which featured Sting, Andy Summers and Stewart Copeland, was well-received and became one of the highest-grossing tours of the time.
"It's not a power thing at all, it's just about producing exactly the brand and style of music that feels right for you," Sting said. "Music, in every form, is a collaborative process, but never more so than in a band, where you have to consider other people almost more than you do yourself."
