I must say that they sound mostly great on what I've heard until now... well, if you don't count Jon's voice.

But as already stated by Xavi, it was better in 2015. Actually, I was a little bit surprised about how well he sang some certain difficult parts (while still failing at others, of course). But I think Jon is really doing something for his voice right now and if that kind of progress continues until February, then the THINFS tour performances will be quite good.

However, I'm still waiting for more recordings. Had no chance to record something or to even watch, so I'm just hoping for the best on this front
