Listening to recent music from alt-rock band PVRIS, it’s hard to imagine that the trio started out as a metalcore band with a male vocalist screaming alongside current lead singer Lynn Gunn. That speaks to how much the band members have evolved since forming PVRIS as teenagers, as their sound has developed into polished, arena-friendly electro-pop with a rock edge, led by Gunn’s smooth, soaring vocals and personally revealing lyrics. They may have spent four straight years touring as part of the hard rock-oriented Vans Warped Tour, but they’re now poised for mainstream pop success. A big part of that is thanks to Gunn’s openness and vulnerability in her lyrics, which strike a chord with the band’s young fans. “I don’t know if it’s what we’re putting out and attracting back, but there’s a lot of camaraderie in our fan base, which creates a really safe and accepting space,” she told The Guardian last year, and PVRIS has followed through on that commitment by dedicating a portion of tour proceeds to LGBTQ organizations. As young as the band members are, they’ve already come a long way, and it’s clear that the future for PVRIS is wide open.
