Pop-punk sensation Paramore are in the studio working on their fourth album.

The band recently dumped (or lost, depending on who you believe) their guitarist and drummer brothers Josh and Zac Farro, but being a three-piece hasn’t stopped them getting back to work.

Paramore’s guitarist Taylor York recently tweeted, “Good afternoon (or whatever time of day it is wherever you may be). Day number 2 of recording. Super stoked. Sounding good! Yeahyeahyeahyeah.”

York is also tracking drums for the album, with singer Hayley Williams tweeting her amazement “He never told us how great he was!”

They’re working with Rob Cavallo, who produced their last album, 2009’s Brand New Eyes.

And they have also been added to the next Warped Tour in the US.
