Though they looked slightly out of place on the lineup, Weezer performed last night at the Alternative Press Music Awards (APMAs) in Cleveland. The most interesting and unusual thing about the band’s appearance is that they were joined by a special guest: Mariel Loveland, frontwoman from New Jersey pop-punk band Candy Hearts.

The teased her appearance by posting a picture of soundcheck:

And the setlist for the show reveals it was planned all along:

Thank you for jamming with us #apmas! @altpress

No word yet on how the connection between Loveland and Weezer came about, but you can watch a brief clip of them performing “Go Away” off last year’s Everything Will Be Alright In The End below. The album version of the song features Bethany Cosentino of Best Coast, but Loveland handles her part with ease.

The lead singer from my favorite local Jersey band just sang with Weezer?! I'm so happy. Good job @candyheartsband! I'm a super proud fan right now. #candyheartsband

Considering Weezer connected with Cosentino via Twitter, maybe that’s how they met Loveland too?
