It's not a music festival like the ones you listed for starters, and while those are like an all-inclusive resort in that you just show up with money, Burning Man is more like camping in that you take everything there (and back).
Nova Rock is mostly camping on and inhaling dry dirt, camping in and being covered in mud, not going to the toilet for 2-3 days, and eating canned food. But I hear you.
