I hate to be this guy, but I don’t think they will do NYE on the west coast. Perhaps a mini run leading up to it, but not on NYE.
Phish is a business, and a pretty smart one too. They probably wouldn’t do a NYE show on in the Pacific Time Zone. Those webcasts are a revenue stream, and they maximize their profits by playing shows on the east coast, because the rest of the country can stream them. Midnight in Cali is 3 am for every state east of Illinois. The people they would want to sell a marquee stream to will be sleeping, drunk, or hooking up with a rando who’s New Years resolution is to be “more adventurous.”
Miami makes the most sense (especially since they tour with their families), but NYEMSG seems kind of likely. Man would that piss off the jaded non-east coast Phanners . Wild cards: Hampton, Atlantic City, and Boston.
