Four years is a measurement of time that America has used for centuries to indicate change. Presidential terms last four years; high school diplomas and college degrees typically take four years apiece, too. It’s not an arbitrary thing, either: It typically takes that much time from the declaration of something changing for it to actually change.Meet Laura Jane Grace. Four years ago, the Against Me! frontwoman came out as transgender; 18 months later, she released the band’s sixth album, the fiery Transgender Dysphoria Blues, one which she began working on before her transition and helped document the struggles she was facing. It was an intensely personal record that took on a life of its own, connecting with thousands of new listeners drawn to Grace’s honesty and complexity while still pleasing Against Me!’s dedicated fanbase.Now, four years after Grace’s public reintroduction, Against Me! is ready to release their new album, Shape Shift With Me, September 16 on Total Treble. While much has changed in the lives of Grace and her bandmates—guitarist James Bowman, bassist Inge Johansson and drummer Atom Willard—in that time period, it’s clear that those intervening years have done wonders for creativity.“Everything with Shape Shift With Me has been really about keeping momentum going,” she says. “In between every tour we did for Transgender Dysphoria Blues, I would have a couple songs I had written and we would demo them. At the end of two years of touring, we had an album ready to record. Usually, you come off of touring for a record and you're back at square one. But this was so fully formed it felt like there was no choice but to go ahead and record the songs.”In a career already full of classic punk records, Shape Shift With Me feels like the definitive Against Me! album—it’s poppy and catchy (“Rebecca,” “Suicide Bomber”), aggressive and in-your-face (“ProVision L-3,” “Dead Rats”), sentimental and longing (“Crash,” “All This And More”). Moreover, it’s the culmination of four years of existence as Laura Jane Grace—there’s no going back now, so she might as well embrace it.“While I’ve always wanted the moon and the stars, I have a certain amount of humbleness,” she admits. “I just want to play shows and make records and write songs. That’s what I’ve always wanted to do. Of course I always want the biggest and best things for those shows and records and songs, but when it comes down to it, I just love doing it. I have no other ambitions or career goals.
