The music is really beautiful, and beautiful voices. The 3 top performers (Hamilton, Burr, and Hamilton's wife) have all left the cast as of just a few weeks ago. That's one reason that tickets are not as unaffordable now. Our Hamilton was Michael Luwoye, not Lin-Manuel, but I really enjoyed ours, who had a much stronger voice than L-MM. Renee Elise Goldsberry, who was off the night we saw it, is really terrific on the soundtrack as the sister of Hamilton's wife. She played the mean assistant state's atty on the Good Wife, who sort of had an affair with Cary. But the woman who played her Monday, was also fantastic.
Finally, the soundtrack is probably about 97% or maybe 100% of the play. There is very little non-rapping, non-singing in the play. So, if you listen to the soundtrack, you know the play.
