Devin Townsend is the most talented musician I've seen live since Neil Young, maybe moreso. Amazing vocal range, very creative compositions, heck of a guitar player, great stage presence, and somehow his "wall-of-sound" production translates directly to the live show.
I've never heard sound levels balanced so perfectly, or vocals sound so clean and crisp live. I think they must have their own separate equipment and do sound check long before showtime, but it's worth it.
Cynic is like the Rush or Yes of 2010, with auto-tuned vocals. Also awesome, lots of jazz improvisation and very impressive drums.
