To me one of the best live shows ever was Earth Wind and Fire, with Chicago. Both were huge influences in my learning to play and write music.
Both bands hat a horn section, which imho was something that made their sounds full, for lack of better word.

Shame that Terry Kath isn't around any more, but they still did great. and having both bands tour together was to me just musical magic.
Philip Bailey still has those great falsetto highs.
here is one the did together. the second one is a whole show, lengthy yes, but worth it in my book.
