I know that in the past, Coachella seems to shy away from heavier acts. With that caveat, I'd like to see any of the below on the 2013 lineup:

Queens of the Stone Age
Probot
Mastodon
Baroness
Kylesa
Torche
Opeth
Meshuggah
Gojira
Dethklok (srs.)
Red Fang
Deftones
High On Fire
Converge
Wolves in the Throne Room
Pelican

...and so on. Please?
