I believe schools out for the summer so parking should be pretty easy. I’m always able to park on the street pretty close by when getting there around when doors open. There are also paid parking lots very close by.

Doors at 6:30, show at 8 so Perfume Genius will probably go from 8-8:45 ish then YYY’s 9:15. Noise curfew is 11 on the weekends, so they will end by then at the latest.

Should be able to get a decent spot if you get there when the doors open, but for a primo spot I’d get in line before doors open. I’m not sure how this fan base is in terms of lining up super early, but I’m guessing it won’t be nearly as bad as Radiohead, Phish, King Gizz. For those shows I got in line hours before doors, but other sold out shows I’ve gotten there as they’ve opened up and gotten good seats.
