Emerson, Lake & Palmer performed on this day in 1974 at the Swing Auditorium in San Bernadino, California.
ELP were at this time on their Brain Salad Surgery Tour, undertaken to support the album of the same name. The group so far had only performed in North America. Their first European concert of the Brain Salad Surgery Tour happened about two months later in mid-April; it occurred at Empire Pool Wembley in London.
There is no known recording of this particular concert.
