Justin Timberlake has always been a hot ticket at Madison Square Garden. But even JT fans who have been unable to land tickets to see him live have likely caught one of his shows at the arena: When he was a member of 'N Sync, their "No Strings Attached" tour was captured in the 2000 DVD "Live from Madison Square Garden," while JT's 2007 MSG show on the "FutureSex/LoveShow" tour also made it to home video.

amNY tracked down a copy of the 'N Sync show (harder than one might think -- we miss you, Blockbuster!) and the 2007 solo concert to compare with a recent show on the "20/20 Experience" tour in Inglewood, Calif., and chart the progress of JT from boy bands to manhood:

Backing Band: Six musicians, four backup danc ... no, that's the rest of 'N SYNC.

Costume: Starts with a white 'do rag, black sleeveless jacket with bedazzled shapes, like a mashup of a pirate and a clown. Then, it goes downhill.

FutureSex/LiveShow (2007)

Backing Band: 11 musicians, nine dancers
