1. Led Zeppelin
Led Zeppelin's 2007 reunion show at London's 02 Arena wasn't intended to be a cruel tease for their fans, but that's ultimately what it became. The group spent months rehearsing, eventually perfecting a two-hour show that was simply spectacular. Tickets were virtually impossible to come across, but fans assumed they'd at least do a few more gigs. Why else would they put so much work into it? Even Cream did seven shows, and those guys absolutely hate each other.
Sadly, the reunion began and ended that night in London. Jimmy Page and John Paul Jones were dying to keep things going, but Robert Plant had other plans. His collaborative album with Allison Krauss was blowing up at the time, finally earning him critical raves and huge album sales outside of Zeppelin. Rumors circulate every year or two that Zeppelin are on the verge of doing more shows, but don't believe them. Robert Plant says he's done and there's no reason to think he's bluffing.
