On March 21, a metalcore frenzy erupted at Irving Plaza. Bands ERRA and Currents, along with special guests Caskets and Aviana, played an explosive show that made for an unforgettable night. Swedish band Aviana kicked things off, hyping up the crowd and starting a mosh pit that seemingly never ended. Caskets followed, calling up crowdsurfer after crowdsurfer through the audience. Then, co-headliner ERRA played. Their set was electric, and the audience kept the energy from the openers going. To me, the heaviness of ERRA's set almost had a romantic touch, as guitarist Jesse Cash had a bouquet of flowers strapped to his mic stand. The softer theme ties into ERRA's recent album, Silence Outlives the Earth, which takes an introspective look at the human condition. Fellow co-headliner Currents continued ERRA's introspective theme, screaming out deeply personal lyrics to the crowd. I got the sense that the audience not only heard the band's words, but that they . The music hit people where they truly needed it, and singer Brian Wille's calls to the crowd to mosh and dance allowed the audience to gain catharsis through movement. In the end, it was a genre-defining night. If you are a fan of metalcore, definitely check out this tour on a date near you.
