Now in its third year, SXSW's K-Pop Night Out wowed audiences thanks to Epik High and Crayon Pop, the latter of which premiered their upcoming single before the official release.

Set to return March 27 with "FM," Crayon Pop performed the song on Thursday at Elysium in Austin, Texas. According to allkpop, the girl group worked with producer Shinsadong Tiger for their comeback.

"How can I stop listening to this?" asked YouTube viewer Ephraim Gonzales under a fancam video of Crayon Pop's SXSW performance.

"The dance is what really fascinates me. So cool!"

Crayon Pop was joined by K-pop veteran hip-hop group Epik High, who performed hits such as "Born Hater" off of their 2014 album, "Shoebox."

"If you're seeing us for the first time at SXSW, it's actually the perfect time to get to know who Epik High is," said Epik High's Tablo to Billboard.

"I'm sure some of our fans are excited, but even more than the fans, we're excited to be performing stateside again. It's been a very long time. During that time, we've grown stronger as a group. Whoever's coming to the show, you're going to be a part of the stage, you're going to be part of the act just as much as we are. That's the best part of playing live."

In addition to performing at SXSW, Epik High is reportedly planning a US tour for the summer.

"We are planning a US tour sometime this early summer," continued Tablo. "We're going to hit as many cities as possible so you should find [us] in a city nearby."

Reportedly, both K-pop groups received praise for their SXSW performances, including being cited as one of Fuse's best moments of SXSW 2015.
