I still only have The Mars Volta and Sigur Ros from this year.
I'll almost certainly be getting the new Lo'jo. edit: I forgot, there is also the new Bob Dylan and the new Dave Matthews Band, both of which I'll most likely get.
Were I to get something else, it would be Tallest Man on Earth, Meshuggah, Anathema, Flying Colors, or Susanne Sundfor.
