Two LP's come to mind: an old Riverside recordings called "The Sounds of Speed", which included stuff like the world-record land speed record by Mickey Thompson; steam locomotive going by; etc. It's long out-of-print, but if you can find a decent copy I guarantee it will wring out your audio system. The other LP that comes to mind is Keith Johnson's recording on Reference Records called "Astounding Sound Show" (or something close to that). It contains 7 cuts from various recordings he has done, and several are really startling.
Ear Candy: Most startling recordings.
OK, we all respect great musical talent and muscianship, but sometimes you put in a CD and you get one of those startling zany recordings that make you smile it is so strange. Some of Neil Young's stuff is kind of like that. Alot of Pink Floyd is like this. Sounds racing across the sounds stage, shifting mike position in mid recording. What are your favorite "ear candy" recordings?
