In The Zone Takeover: NFL Kickoff Concert

In The Zone Takeover: NFL Kickoff Concert

Britney officially kicked off the "In The Zone" era with her performance at the NFL kickoff, starting off with her very first performance of "Me Against The Music" (sans Madonna), then went straight into "Baby One More Time" and "Slave."

Fun fact: the remix of "Slave" in this performance is where the name "BreatheHeavy" came from (starts at 2:47).

Check out photos of the performance in XRAY:
