The guests on that "What Are You Listening To" YT show I posted somewhere were talking about some "giant separate HC scene" and I imagine Turnstile fits that - are they sponsored by anyone? It's a band name that would fall under, don't wanna hear them just from the name but had to investigate...This is a huge show and the sound is definitely more of a hybrid...
googling them, there is a big sponsorship company with the same name!
