I'm a fan. I admit the album doesn't grab me in the same way some others do, but I find it very listenable, for the technical side if not exclusively the music. I enjoy hearing what he does, and figuring out the way he does it (I was familiar with octaving a guitar down, but POGing your bass up?! Witchcraft!).
If nothing else, I wouldn't have discovered BassChat if it wasn't for googling 'Royal Blood effects', and now I'm completely hooked on learning about bass effects, new rigs, the best way to hook up to sound desks, trawling the basses which come up for sale... So I guess I have Royal Blood to 'thank' for that...
