Re: Q's voice... I think it's even better than on the record, it's awesome. I love the fact they're shying away from putting too much effect on it, it brings it out much clearer than on the record.
edit: however, the audio was a bit rougher in Coachella, I'm guessing it has to do with the festival environment. it could be the reason for the off-keyness at points. she kills it in Welcome Oblivion though. god damn.
