I'm just PRAYING this isn't full of triplet kick runs. Not that I don't like Adler but I've been a PTH fan since before Kezia and I miss their punk roots.... Will be really upset if it's just triplets and ride bells.
I'm sure he is going to play with their sound in mind vs what log would play. Also, I would guess they probably have a good bit written already so he can probably just play along to some of it.
On another note, this is pretty kickass fill in.
