I've got a fever... and the only prescription... is more Trey on cowbell!
They definitely need to keep the mini drum kit moments. Additional percussion creates a nice effect, for a stretch of time the jam gets simultaneosly more rhythmically dense and yet otherwise a bit more sparse/atmospheric. And the main attraction is Page gets to shine with some synths, of course. I believe sometimes it's cool for Trey to step back a bit, so that when he returns to guitar, it's that more powerful. So, i'd welcome them continuing with this and/or with any variation/equivalent to it.
Not gonna break new ground, but, man, those YEM/C&P jams from 7/29 are unbelievable. I was not that crazy about many of the previous 25+min monsters this summer (namely, i felt that SOaM and Carini had some weaker spots or not the best pacing), but that night they totally brought it!
Now, i wouldn't overstate the mini drum kit role here and i don't want it to sound like it "saved them" lol Obviously they still had plenty of peak moments regardless.. but it really felt like more often than not these would kick in an extra gear, push them in an interesting direction or simply add more variety and dynamics.
