As the leading Zep fan, I would say they are serious about their sound. Guitar tones are excellent. The singer doesn't necessarily sound like Plant but he can hit every note. They did some songs that were less well known which I appreciated.
I would say if your expectations are seeing a Led Zeppelin cover band then you would be very pleased... I love their attention to detail, musically speaking. Visually they don't try too hard and I kind of appreciate that too... 3 guitarist dressed like Page?
