Everyone will probably make fun of me, but the Justin Timberlake/Christina tour that was around a couple of years ago was one of the best shows I've seen. Easily in my top 5. Oh, and a little band called the Black Eyed Peas opened for them both.
Yes, I was VERY surprised. Christina's voice is pretty impressive, and didn't disappoint live...
JT was off his freakin' rocker. I haven't seen someone work a crowd that well since the likes of Michael Jackson. Bold statement, I know, but he's really legit live.
Most impressive thing about that show? There are two things.
1) He opened, yes opened, with his huge hit at the time, "Rock Your Body". If you've seen enough concerts, you're aware that the status quo is to save the hit for the end of the show, or near it. The second he went from his dance thing into that, as his first song, I turned to the people I was with and stated, "OK...now THAT takes balls. You must think the rest of the show is pretty stellar to play your only sure thing at the very beginning."
2) Ole boy can beatbox. He spent twenty minutes suspended over the crowd, battling with his drummer and DJ on old school club tracks like "Planet Rock" and "It Takes Two". Veeeeeery cool.
Pop prince or not...this guy's a good musician, and knows how to rock a crowd. I'd see him again live in a second.
