The words "secret show" and "Kendrick Lamar" together in one sentence is enough to put fans into a bit of a frenzy.

While the performance itself just might be the definition of rare, many fans were lucky to get tickets — with a catch, of course.

As reported, after weeks of rumors swirled online, the Compton rapper's secret is out. He'll be performing at the Music Hall of Williamsburg in Brooklyn tomorrow night (Dec. 16).

For the intimate show, cardholders of American Express were exclusively invited to purchase tickets. For those who missed out, the entire concert, luckily, will be live streamed on Kendrick Lamar's and AMEX's Facebook pages.

Hopefully Kendrick Lamar will be doing an official tour soon. We're certainly ready for that possibility in 2017.
