I have nothing against catagorizing by collectors and scholars, but I do feel that it is wrong to force catagories onto performers and participants.

I don't think the restaurant analogy works exactly. If I go to an Italian restaurant and order linguini with clam sauce, the chef usually follows a standard recipe that does not vary much from establishment to establishmetn. If I order the chef's surprise, then I take what I get. Before I place my order, I know the ingredients and there is little surprise.

When I go to a concert, I usually have an idea of what the music is about. If I've never heard the performer, then I've just ordered the "chef's surprise" and take what is put in front of me. I may like it or I may not, but at that point I would not have been expecting pizza and delivered chicken parm.

Likewise, I would not order bagels in Des Moines and expect them to taste like a good NYC bagel.
