A few I've missed -
Johnny Coppin - Local folk guy who was talented but incredibly pesdestrian. His encore consisted of perhaps the whitest cover of Rockin' Robin I'll ever hear.
Aloe Blacc - The man's cool, has a great voice, and generally wowed the audience. I felt a little more reserved, primarily because he would talk for ages between songs, droning on and on about "being here, right here, in the moment" and other such drivel. He also made the audience clap through basically every song.
La Nuova Musica - A classical ensemble who performed Handel's Messiah. Pretty awesome, I must admit. Everyone stood for the Halleliujah chorus, and then gave them a huge ovation at the end (though some idiot kept shouting "MORE!").
I've got a whole bunch more coming next year, starting with Fleetwood Mac performing the entire Rumours album.
