Having grown up in the south (US), I can say this sounds extremely authentic, very much what I and my 14 year friends would hear at our first concerts, drunk one one beer. Clear mix and engaging arrangement, well done! By the way, I'm now living not terribly far from you and I know what you mean by the heat, it was intense, especially with no air conditioning. Spraying your t-shirt with water and sitting in front of a fan causes accelerated evaporative cooling which helps a lot, unless it is very humid. Something else which helped me through the worst days was sitting with my feet in a small plastic tub with a few centimetres of tap water (not chilled), then adding a 500 ml frozen water bottle. Because your feet are pulse points, this will pump cool blood throughout your body effortlessly. Even after the bottle fully thaws, it helps a lot. Obviously not the most convenient thing, but if you got to the stage of living inside your freezer I suspect things reached the point where convenience became less important than relief !
