Did this thread last year...got some great feedback on it...haven't seen one started yet this year so thought I'd launch it up again for 2014.
Big surprise for me this year is how few acts I've already seen. Girl Talk, Ellie Goulding, and Chromeo only three on Friday (and none whom I'd give exceptional marks).
Muse - If you like their music, you'll love their show...good energy, great chops, lots of laser-y and rear-screen pyrotechnics...but aside from a few songs, I don't like their music, and found their 2010 set at Coachella dull despite all the effort on their part.
MGMT - Believe every bad thing you've heard...one of the most disinterested live acts I had ever seen, until I caught Destroyer.
Sleigh Bells - Solid, good energy, some very fun songs (though mostly their earlier stuff that won't get as much play this time out)
Cage The Elephant - I caught them when they were a much smaller name playing the Mojave around 2 back in 2009 and loved them then...haven't seen since cause haven't cared much for most of their more recent material but friends who have haven't been particularly forthcoming with praise...Sounds like lead singer's voice is up and down depending on when you catch them.
City and Colour - a smaller artist whom I really question bringing back for a second stint though I think I know why (an ex-punker from PT's younger promoter days), but I will say this, has a phenomenal voice...if you're looking for some downtime and a great midday chill-out set...this might be the call.
Warpaint - Fan-fucking-tastic...so much better live than on record...they get this crazy separation of sound thing going live...you can hear every detail from every instrument...sonically spellbinding in person even though a lot of their songs are just so-so.
Only act I've seen before Sunday is Arcade Fire (3 times previous) - not a huge fan of either Win Butler or RC's stage presence...Win can come off very uptight (though he was much more relaxed at Coachella 2010) and RC's just so pretentious, her mannerism's really bug me after a while...but there's no denying that when these guys get cooking, they're one of the top arena-sized live acts around, and even though Reflektor, for me, is their worst album yet, it's got a few songs, particularly Normal Person and the whisper-hush end of Hey Orpheus, that I cannot wait to hear live.
