See BAD OMENS' Noah Sebastian join BRING ME THE HORIZON onstage for "Antivist"

Bring Me the Horizon kicked off their U.K. tour last night (January 9th) in Cardiff, Wales, where they were joined by supporting acts Cassyette, Static Dress and, most prominently, Bad Omens.

The U.S. band helmed by Noah Sebastian are one of the fastest-rising bands in heavy music, and the group have been abundandly clear that BMTH were a crucial influence on their early material. 

Therefore, it was a particularly special moment when Sebastian trotted out onstage during BMTH's set for an epic tag-team of the Sempiternal ripper "Antivist." 

"We've brought this band all the way from America," BMTH frontman Oli Sykes shouted. "He's jetlagged, he's dead, he wants to see a real fucking circle pit!"

From there, he and Sebastian (who was donning a yellow ski mask) went back and forth on the mic screaming the rousing words to "Antivist" while the crowd went wild. Clearly, it was a crossover that many fans had been waiting to see for years.
