It was a non-stop summer for EDM duo NERVO, from jet-setting around the world to being house DJs at the 2013 Video Music Awards pre-show. But now it's back to business for the Australian twin sisters.

Ahead of the release of their debut album, Liv and Mim (who are brand ambassadors for COVERGIRL) just released "Not Taking This No More," a fast-paced, high-energy track that they worked on with fellow Australian producer Ivan Gough.

"We actually met him on an airplane flight from Brazil to Australia in February of this year and reconnected that way, went home, wrote the track," Liv told MTV News last month of the follow-up to "Hold on." "And the top line was actually sung by a singer called Beverly Knight in the U.K., a big soul vocalist. It's a little touch of old house, which is the house music that we fell in love with."

The video for the single was shot over the summer during their residency in Ibiza, where they also spent a lot of time working on their debut album. While it doesn't have a release date yet — they told MTV News back in May that they "keep changing our mind" — there will be more music to hold them over until then.

"I think we have three singles scheduled until the end of the year, so it's busy, busy, busy," Mim said. "But lots of great music."

NERVO, who will be primarily showing off their own vocals on their debut, have worked with some of the biggest hitmakers in music from David Guetta to Ke$ha, and while they did say they've recently collaborated with other artists, they weren't ready to reveal exactly who it was.

"Unfortunately we are not allowed to talk about it because there is a rule if you talk about it, it doesn't happen," Liv said. "You just jinx it."
