Not two weeks after the release of their rousing new album Peanut Butter, jangle-punk rockers Joanna Gruesome have just announced American dates starting in late October, including a stop at this year's edition of Fun Fun Fun Fest in Austin. The new dates follow a July 4 appearance at Denmark's Roskilde festival and a tour of the U.K. in September.

The announcement accompanies a Facebook post explaining the circumstances surrounding the amicable departure of vocalist Alanna McArdle. In McArdle's place, the band is joined by two new members: Kate of Pennycress on "melodic vocals/shouting/screaming" and Roxy of Two White Cranes, Grubs, Trust Fund and the "misandrist power trio" TOWEL on melodic vocals and keyboards.

hey so we've had a line-up change and we're super super sad to say that alanna will no longer be playing in the band.

lan joined the band after seeing us play somewhere in london years ago after our previous singer moved away, and since then has been the most amazing vocalist/person/band member/gruesome we could have ever asked for. just on like a musical level, it's been incredible writin songs and melodies for someone with such a powerful voice to sing, and her amazin lyrics have always totally improved the aggressive sections of our music. but also in every other way, it's been so so cool to be in a band with someone we've became such great friends with, someone who's been totally unafraid to hone in on horrible jerks and someone who's made negotiating the bullshit of music industry types fun and inspiring. it's taught us loads, we've had some of the best times and we totally support her decision. she's been an amazing person to be in a band with. we will miss her greatly.

here's a message from her:

'Lately, my mental health problems have become a lot worse and I've gone through a pretty shitty time. I've realised I need to actually take some time out to focus on some kind of 'recovery', so I won't be singing in Joanna Gruesome anymore. I hate to sound cheesy but the time I had in jgro was life-changing. I made friends with so many amazing people, had the chance to play with some of my favourite bands, went to places I'd never been before (metaphysically and geographically) and pissed off a lot of men in the process. I am really proud of everything I've done with the band, especially Peanut Butter, and I think we've made some really great records. Thanks to everyone who ever put up with me on tour, and anyone who stopped any assholes from hurting other people at our shows xo'
