In July 1974, when Emerson Lake & Palmer delivered the electrifying performance of "Karn Evil 9 1st Impression" at Rich Stadium in Orchard Park, New York, they were riding high on the success of their ambitious album “Brain Salad Surgery,” released just a few months prior in November 1973. This album not only showcased their progressive rock prowess but also included the legendary track "Karn Evil 9." The live performance exuded the dynamic synthesis of Keith Emerson's virtuosic keyboards, Greg Lake's emotive vocals, and Carl Palmer's explosive drumming. Interestingly, “Brain Salad Surgery” marked a pivotal moment in ELP’s career, featuring intricate compositions and elaborate stage setups that both thrilled and inspired their audience. By this time, their reputation for grandiose live shows had solidified, leading them to become one of the defining bands of the progressive rock era.
