Metalcore isn’t exactly the most mainstream of genres, but Darkest Hour have managed to do the unthinkable—make hardcore sell. They’re one of metalcore’s most commercially and critically successful bands, and now, DC’s own Darkest Hour return to New York to celebrate the release of The Eternal Return, their sixth and newest album. Despite some early troubles, including line-up changes and being dropped by their first record label after bankruptcy, the band has won a rabid fan base with a melodic twist on traditional hardcore metal. Fresh from a long tour across Europe, the band is returning to the U.S. and playing two nights at Irving Plaza on July 19 and 20 to finish off their long Summer Slaughter tour. Tickets are $30. Admission is for those 16 or over only. Visit darkesthour.cc for more.
