Beck Live.

The music sounded great. He played at least something off each album. And the Puppets were amazing.
You can read more about them here (thx to Heather , who looked super cute in her green sweater at Rhinebeck!, for the link), and here where they also discuss another unusual happening in the concert: when the band (and the puppets as well) ate dinner on stage.
This ranks pretty high on my “funnest concerts EVER” list. Loved it.
Oh, except for the part where it was at the UIC Pavilion and there was NO BEER ALLOWED. That part sucked. Me loves me a beer.
