ok admittedly I havent listened to them recently. But then what tour should they do? what bands do they tour with? what fans would latch onto them?
The only answer i see is Warped tour. Its not like theyll ever play Coachella or Lollapalooza, or tour with the 'cooler' metal bands ala Converge.
I'm sure BMTH has/will offer Converge an opening spot on a tour, but I'm also positive that Converge would turn that down. If we're talking about supporting tours, I could see them opening for Linkin Park or Slipknot, or Maiden, one of the arena-metal bands. For openers, I'd imagine they'd bring out the other "bigger" numetalcore bands like Parkway, TDWP, Pierce the Veil or whatever.
Also KAZI, BMTH is still scene haha any change will be purely image, and maybe some atmospheric synths to make it "post rock".
