In 1974, when Emerson Lake & Palmer performed "Karn Evil 9 1st Impression Pt. 2" live at the Ontario Motor Speedway during the California Jam festival, they were riding high on the success of their album "Brain Salad Surgery." Released just a few months prior, in November 1973, this album marked a significant point in their career, solidifying their reputation as pioneers of progressive rock. Notably, it included the epic "Karn Evil 9," a multi-part suite that showcased their unique blend of classical influences, innovative synthesis, and rock bravado. The California Jam performance was a landmark event, capturing a moment when ELP's theatricality and musicianship captivated thousands, including future fans witnessing their dynamic stage presence. It's fascinating how the energy of that live setting added layers to their already intricately composed music, making performances like this one a pivotal experience for both the band and their audience.
