It's tempting, just to see Them Crooked Vultures, FAITH NO MORE!!!!, Dead Weather, and Muse. But they would have to add Soundgarden or something for me to really think about spending the money for tickets, somewhere to stay, and plane tix.
Honestly each time I see the lineup for Coachella, there are just way too many bands that I don't give shit about filling up space, for me to justify throwing down so much money.
Since I live much closer to Chicago, I usually go to Lollapalooza if I go to any festival. Not only are tickets cheaper, but much cheaper for me to get there and to stay there.
