The 'Hamilton' Grammy performance won over a new set of fans

The cast of the hip-hop musical composed by and starring Lin-Manuel Miranda performed the opening number Alexander Hamilton for the Grammys from New York's Richard Rodgers Theatre.

To no one's surprise, they killed it. And got a lot of people on Twitter asking, "Just what is Hamilton?" followed quickly by "How can I get my tickets NOW?"

Hamilton is notable for having a diverse cast, despite being a historical musical about one of the country's Founding Fathers, Alexander Hamilton.

Shortly after the performance, Hamilton was awarded the Grammy for best musical theater album. Miranda went and rapped the acceptance speech (he also rapped his Tonys acceptance speech for In the Heights back in 2008), populating the #Ham4Gram with even more would-be fans.

Here is Miranda's full acceptance rap:

"We write music, we write songs to tell the story. Whether you’re King, Kendrick, or Jeanine Tesori. I’m sorry if I start screaming these thanks hysterically: John Buzzetti, Tim Latham, Tom Coyne and Derek Lee. Tommy Kail set the stage to kick our boots through. Bill Sherman, Quest, and Tariq, the whole Roots crew. Sean at Warner Chapel, Riggs and Craig at Atlantic. Lacamoire my right-hand man. This frantic Hispanic is non-stop. The best idea goes in the pot. The cast unstoppable. Band is unbeatable. Inimitable. Inevitable. Always inspiring me to pull through. Vanessa, Angie, Illie, Ellie, we adore you. Sebastian, Daddy’s bringing home a Grammy for you.

We're even more ready to be in the room where it happens.
