Are you looking for something grimy and heavy to mosh to? This Connecticut band may be what you're looking for – Endless. They mold Hardcore / Metalcore elements to open pits and crush eardrums. This is more than apparent from their newest release / debut EP "Realist". Up until this point they've released a number of hard hitting singles, but now it has come together full force.
Listen to the EP stream (via Bandcamp) below and see if you start moshing involuntarily. If this seems to be your cup of tea, here's some good news! All of "Realist" is available for a "name your price" download! Go grab it HERE and support the band!
