Not at all, I would quote it as an homage, I have seen what your talking about though, should have clarified. I agree 100% with everything in said post.
But in response to what you said now, all personal preferences and technicalities aside, Led Zeppelin is the total package. The acts you mentioned are similar but not on Zeppelin's level. Critically acclaimed in their time, and even more so now. Commercially one the ten best selling artists ever worldwide, tops in the HArd rock genre ever. The second most influential (regardless of quality) band (behind the Beatles) on future generations ever.
Look I rarely get into this discussion because it frustrates me but, Led Zeppelin live is unlike anything else I have ever experienced in music, and there are not many who saw those shows from 1970-1975 that would argue or have a differing opinion. It wasn't because they were the first to as another poster put it "F*** the S*** out of the Blues" or wrote the best songs or played the best type of music, it was because they did what they did in a way that spoke to millions and millions of people, no one else has to like it, enough people already do to make the point.
