All a bit too clever for me. There's no denying the skill but I really don't like that augmented bass sound, whatever or however it's done - it feels on the one hand, as though they're about to launch into a metal moment at any point, and on the other, I'm reminded of Gorelick - Kenny G. Plus I'm not sure whether the point is the music, or simply to show off. There's a lot of frippery here, IMHO. Maybe that's what's happened to Robert - he seems to have lost his marbles and Fripped out completely! Lol! Polyfilla. That's so rude of me, sorry - could not help it!
