One of my favorite shows of all time - Kiel 1993:

Even though Jon's vocal consistency had already gone down quite audibly by late August when compared to the constant epicness of April and May, at this show he went all out and delivered a truly magnificent performance all the way through. The encore performances of ITA and IBTFY were something totally out of this world, I'd Die For You was pure passion (just listen to his breathtaking scream at the end of the song!!!), and I absolutely love the extraordinarily high level of energy that he, alongside the whole band, had even on the "mandatory" songs like Bad Name, Medicine (Rock Some More and everything included) and Prayer

Amazing show!
EDIT: Jesus Christ, this ITA is just... just... I don't know...
