I saw the Vivian Girls a couple months ago in Santa Cruz and they are super awesome, the crowd energy was intense in that tiny place. They were also really sweet at the merch table afterwards!
I would call the venue. They might release some at the door, but it seems like they've been doing that less nowadays.
Or sometimes (sometimes) you can get lucky and they'll sell you a ticket once the headliner has gone on and a significant amount of people have left the show.
yay!! the vivian girls were adorable. unfortunately, they're sizeists... there was no XL t-shirt available at the merch table, and i was informed in a way that inferred there never had been! :(
Thanks! I updated the post. Saw Lucky Dragons at the Whitney Museum a few weeks ago and they were so cool, but only played for about 20 min. Looking forward to a longer set! Tip: sit up close and you'll probably get to participate :)
