50 in 50: Have you been to a memorable concert?

I don't tend to go to a whole lot of concerts; recently I have started going to performances of classical music that are all incredible.

I would say, when I went to go see The Darkness (thrice, now), I found that quite memorable, too. I also enjoy how he calls out the people on their phones the whole time: funnily, the last time we went to see him, people spent their time recording him chastise them for incessantly recording.

Apart from that, the only thing that comes to mind is a performance I saw very recently called Piano at Six, at the Guildhall. The pianists were fantastic! Completely in flow with the instrument.
