Those great Stax collections are worth a listen, too, e.g.,
Booker T and the MG's "Green Onions."
Such taste...A woman I work with once asked in a meeting what we would choose as our entrance music - as in, if we were being introduced as a guest on a talk show or a keynot speaker, what music would accompany our entrance?
"Green Onions" was my choice for entrance music.
