Muse are a strange choice for a most legendary gig of all time spot. I quite like them as a band, but they are not on the level of The Pistols or the Bowie's of this world. The Pistols gigs were something quite new for the time with the energy and accompanying attention and violence and Bowie dramatically declared that he was retiring. Legendary gigs need a certain notoriety IMO and should come with baggage, myth and speculation. I say the same about Oasis too. It was a huge concert, but that's pretty much all it was.
