Undoubtedly there are many talented musicians on the Tribute scene, who do an excellent job, so I'm not knocking them but I've got no interest in going to see them.
Back in the 70's I endured a twenty minute Jimmy Page solo played with a violin bow, it was a miserable thing then and the thought of sitting through it all again, with some pretender dishing out the torment, makes me feel a bit ill
For me, it has to be the real deal or not at all.
I feel the same about pretend, vintage instruments.
I can take the bashing that's heading my way, so fill your boots
