I won't go because there's only a handful of bands I'd want to see, and they likely all won't play the same day. Plus, as mentioned before, Pearl Jam is doing a larger tour this year. Plus, Nicole Atkins is already playing R&R Hotel and I've seen Metallica twice and at least a dozen of the other bands.
Who I'd see:
Pearl Jam
Robert Planet & Alison Krauss
The Raconteurs
O.A.R.
Iron & Wine
Talib Kweli
Mastodon
Robert Randolph
Nicole Atkins
Please outdo this, V Fest.
