Here’s a playlist of the best new rock that hasn’t yet made the leap above ground. The tracks here represent a younger generation turning an old attitude into something new. Pain, rebellion, flipping convention on its head: Artists have done it for generations, but none—especially considering the influence of hip-hop and electronic music—have done it before the way it’s being done now. Listen up. Our editors update tracks here regularly, so if you hear something you like, add it to your library.
