You don't need to be reminded it's ArtHop night or day or whatever... really you can say day since it'll be sunny and 100 or something at 6 tonight when ArtHop is in full swing. So yeah, go to some art stuff.
After that there are a couple music options, not as many as a usual post hop, but...
Fresno ska rock-steady (guess it's a thing) outfit, King Sugar will be skanking from 9 till whenever. No cover and drink specials throughout the night.
Morbid fun punk rock (wait... morbid fun?) band out of Santa Cruz: Stellar Corpses. Surely they're playing with other bands but nobody seems to know (at the time of writing this) who they are or how much it'll be. We'll just assume 9PM, $5 with [insert Fresno rockabilly punk band here] and those awesome dudes from [insert Madera physcobilly band here] and call it good.
