Too much gain, and the singer needs vibrato on those long notes. Doesn't really do it for me.
Glad they're paying tribute though. It's important to recognize the real roots of where your music comes from... but not by pillaging other's success for money like a lot of pop artists do these days.
Also, that second video is an example of how criminally underrated Kansas are. Great instrumentation, arrangements, excellent musicianship, and killer hooks.
