Far from being a haven for outsiders, American punk has become a highly normative genre, where difference is easily punished. Enter Against Me!, melodic, political Florida punks of some years' standing. Roughly a year and a half ago, their singer announced she wanted to live as a woman. Laura Jane Grace's voice remains unchanged but this refreshing concept album now explores the complexities of double lives, love and loyalty (the shout-along Unconditional Love, the title track), while remaining as accessible and pogo-friendly as Green Day. It's not all about transitioning – power ballad Black Me Out is very cross at some fat-fingered industry type – but Transgender Dysphoria Blues lives up to its title with candour and tunes.
