I went to a music thing - traditional Bengali/Indian music, sita tabla harmonium - that kind of thing - because I was invited and it was one of those invites you can't get out of. So I wasn't really expecting to have a good time.
But it was very interesting and completely contrary to my stereotypes or expectations of traditional Indian music. I guess I expected some kind of formality, rigid and atonal, amateurish but it was like a jam session! It was like jazz - impromtu - it was amazing and it was only because it was amazing that I realised what my stereotypes were in the first place.
