Page randomizer in wordpress

I'm in need of a page randomizer. The randomizer needs to choose a random page out of a list of my creation. Also a very important thing is that I need it to eliminate certain types of pages.

For example: I want to buy a ticket for a concert. But I don't know which concert I should go to. I do however like pop music and I live in New York. so I want to see pop tickets around New York.

I really hope there is just a plugin or add on.

Thanks in advance!
