The Doors- I've been collecting their live albums, and they sound awesome (both quality of recording and performance). Those extended jams and Krieger's guitar are insanely good.
Nine Inch Nails- For some songs. The live "Wish" and "Gave Up" from AATCHB are my go to, if I want to listen to those songs.
KISS- But how "live" are the "live" albums?
Dean Martin- Live versions are a lot more fun.
