Xibalba just released a new song of their upcoming LP Tierra Y Libertad, titled "Invierno." Although they have stepped even further away from hardcore and more into the realm of death metal, I can still hear their hardcore roots and sound from their first release and I love it. I'm a fan of their entire discography so far and I hope they keep at it and continue making solid tracks. Also, being on a label like Southern Lord was bound to catch up with them and I think they took that influence and made a hell of an impact on hardcore and death metal.
Here is that track, released on Noisey
