Nolly's leave sucks in general because he is a very good musician and a nice guy. But, I've been prepared for this decision from Periphery. They are so much into using backing tracks live, not only bass tracks, that having no live bass isn't a problem. I saw them once live in Poland in 2015 during tour with Devin. Great show, but the only problem that I felt about it, was a lack of bass in front mix. It was strange for me, because They all are using Fractal's and backing tracks. I expected perfect live sound, it was very far away from that.
