This Kansas tribute band called Leftoverture from Pittsburgh, PA made it look easy. Unfortunately, they were short lived and broke up before they ever became known for their ability to reproduce Kansas' very intricate sound - especially in a live setting, like a local bar. The videos are from 20 years ago so it's pretty safe to assume they wouldn't still be around today even if they had stayed together back then.
Anyway, I just thought I'd post a couple of their performances here to share with anybody else who appreciates and enjoys Kansas.
The lead singer, who nails Steve Walsh's vocals, reminds me of a cross between a short Axl Rose and Breckin Meyer - kinda, sorta
