Yesterday I attended the Paul Romero concert with an orchestra. This is the guy who wrote every and each soundtrack for HoMM 2-6. And they were mostly playing Heroes 3 OSTs.
Guys, I have never seen and heard anything this wonderful. There were unusual instruments, Paul was telling us how exactly he came for an idea for every faction soundtrack, he was joking, he brought a Saxophonist friend they were doing OSTs for Heroes II together. All in all, I was nearly crying with happiness as was my mom (it was my gift to her).
If you are a fan of HoMM series and you will ever get a chance to attend such a concert, never think twice.
I don't have videos on me, but here is my favorite soundtrack (HE PLAYED IT TWICE YESTERDAY OMG):
