I can forgive an off song or even two, but Landover is a horror from start to finish. That night and the Cleveland show from the weird category I will never listen to again. My criteria for a bad show are First and foremost, Jimmy not being up to snuff on a particular night. 2nd: Plant is hoarse and Jimmy's playing is weak/average, and last would be Plant is barely audible/croaking throughout most of the show w/ Jimmy playing okay/acceptable. I can love most anything Zep or find something good in every other show other than the aforementioned.
