I think it will slowly snowball, they have a solid foothold with hardcore kids, Triple B (who put out their stuff previously) are one of the more popular labels in hardcore but they have a much wider appeal than that, just a matter of RFC getting the music into peoples ears. They tour a lot too, that'll help.
I was going to Brighton to see Touche Amore and just saw they're playing the next day so I guess I'm staying the night now.
