This is such a great idea. A tip if you are not already aware (and interested in music) is to check out “The List”, a Bay Area concert guide which has been maintained since the 90s: http://www.foopee.com/punk/the-list/
EDIT: Got me some Death Grip tickets!
But I think Death Grips is worth a show, given their reputation for live shows.
I'm already dreading standing in GA after they start two hours late, holding my pee to maintain my good spot LOL
