It you haven’t heard of The Last Dinner Party yet, it’s time to listen up. You don’t want to be late to this one.

The UK-based band seemingly popped out of nowhere, but their recently released debut album, Prelude to Ecstacy, is so polished and refreshing. The album is theatrical, powerful, and is fueled with emotion while still being full of some seriously danceable songs. Some tracks are reminiscent of legends like Queen and Fleetwood Mac while others feel like they fit right into the femme-pop world of Chappell Roan and Lana Del Rey. However, The Last Dinner Party are in a world of their own and they introduced that world to a sold-out show in Boston on Sunday night. The female quintet showed no signs of being new to the game. Their stage presence was electric. The crowd sang along to every word from the album, which was played in its entirety. At the end of the set, the band looked innocently astonished at the packed room that had erupted in applause. It’s doubtful they’ll play at a venue this small again, so it made the set feel that much more intimate and special.

Check out photos from their set below, as well as a couple from the night’s opener, Miss Grit.
