Hamilton first timer

Excuse me if this question has been answered elsewhere.

I'm seeing Hamilton (on tour) for the first time on Sunday. If I don't do any homework in advance will I be lost? Should I listen to the cast recording? Read a synopsis? I generally like to go into a show as unspoiled as possible, but I don't want to be totally out to lunch. 

Thanks in advance.

Your predisposition is to see shows unspoiled, and I see no reason not to do that for Hamilton.

I can only give my experience, though, because I broke my own "rules" because the show was really expensive in 2016 (not that it didn't get more expensive later) and I didn't want to pay big bucks for a show my wife and daughter would dislike.

I did listen to the cast recording. Advantages: I knew the words, which do come at you fast in many of the songs, and could concentrate on what was happening on stage. But my unspoiled wife and daughter were never lost, even though my wife in particular had trouble keeping up. It certainly helps to know a little about Alexander Hamilton and the basics of early U.S. political history, though the musical is not a documentary.

I first saw the show on Broadway about a week after the album dropped (first week of October 2015, after the engagement began in late summer). I had heard the title song and pieces of the score on-line before the Sunday matinee. It didn't impact my enjoyment, and, arguably, this is a score that delivers a special wallop on a first hearing. If anything, it may be harder to appreciate if you've memorized large chunks of it. You create a Hamilton in your head that spars with the one performing. Go, and don't worry about what you miss.
