Called “mesmerizingly melodic” by Metal Injection and “approachably harsh” by Alternative Control, progressive death metal band Xenosis has no shortage of mind-bending riffs. The New Haven five-piece formed in 2009 and released their first album, Haunted Skies, in 2012. That was followed by Sowing the Seeds of Destruction in 2015, a tech-death masterwork that garnered renown in the local music scene and beyond.

Balancing precision and brutality, Xenosis performs across New England and also brings high-quality regional acts to Connecticut audiences. If Xenosis is coming to a venue near you, don’t miss your chance to see them!
