Difficulties with my Ethnography

So far in my pursuit of knowledge about the Irish music-culture here in Dallas, I have not come across any severe problems. I attended the Irish Festival on both Friday and Sunday, despite the dreary and rainy weather. I was able to listen to three very interesting bands. I also watched a performance of some Irish clog dancing, which was accompanied by music, so I might throw that in my ethnography as well. The biggest problem I think I'm going to come across is trying to distinguish the differences between the local Irish music and the original culture. A lot of the groups performing at the festival were either from Canada or Ireland, so my ears got a taste of the local and the overseas pretty simultaneously. As for the interviews, I have sent out my emails and have not gotten any responses back yet. Hopefully they will come in soon, or I might be having a very long Wednesday night.
