Kool-Aid is an album by Big Audio Dynamite II. It was their first album under this name and with this line-up, which had been changed by band leader Mick Jones in 1990. It was only released in the UK, Europe and Australia. Several of the songs appeared on the group's next worldwide release, The Globe, albeit in reworked form. Among them is "Change of Atmosphere", which was reworked into the group's number 1 hit "Rush". The Kool-Aid track "Kickin' In" is a significantly reworked version of "Free," a song Big Audio Dynamite previously recorded for the soundtrack of the 1990 film Flashback.
Trouser Press wrote that "with a relatively loose feel and concept, Kool-Aid is Jones' most diverse outing ever, a limited-edition eight-song stopgap offering two acoustic ballads, acid-dance, techno-rock, Kraftwerk samples and even Laurie Anderson-styled poltergeist vocals, as well as a remixed (and retitled) version of "Free," the band's contribution to the Flashback soundtrack."
