top 3 are easy - in order:
1) radiohead @ superpages center, dallas
2) sigur ros @ grand ballroom, nyc
3) radiohead @ bristow
i'll have to think about the rest of my list. early candidates for inclusion are sonic youth, digitalism, thievery/tvotr/ladytron, tom morello et al., and black angels. not sure these counts as shows, but the Justice and SMD dj sets i caught in chicago were really really great, definite musical highlights for me.
i can guarantee you that marnie stern isn't on my list.
