<P> Monterey also marked a significant changing of the guard in British music . The Who and Eric Burdon and the Animals represented the UK, with the Beatles and the Rolling Stones conspicuously absent . The Stones' Brian Jones wafted through the crowd, resplendent in full psychedelic regalia, and appeared on stage briefly to introduce Jimi Hendrix . It would be two more years before the Stones hit the road, by which time Jones was dead, and the Beatles never toured again . Meanwhile, the Who leapt into the breach and became the top British touring act of the period . </P> <P> Also notable was the festival's innovative sound system, designed and built by audio engineer Abe Jacob, who started his career doing live sound for San Francisco bands and went on to become a leading sound designer for the American theater . Jacob's groundbreaking Monterey sound system was the progenitor of all the large - scale PAs that followed . It was a key factor in the festival's success and it was greatly appreciated by the artists--in the Monterey film, David Crosby can clearly be seen saying "Great sound system!" to bandmate Chris Hillman at the start of the Byrds' soundcheck . Lighting by Chip Monck attracted the attention of the Woodstock Festival promoters . </P> <P> Electronic music pioneers Paul Beaver and Bernie Krause set up a booth at Monterey to demonstrate the new electronic music synthesizer developed by Robert Moog . Beaver and Krause had bought one of Moog's first synthesizers in 1966 and had spent a fruitless year trying to get someone in Hollywood interested in using it . Through their demonstration booth at Monterey, they gained the interest of acts including the Doors, the Byrds, the Rolling Stones, Simon & Garfunkel, and others . This quickly built into a steady stream of business, and the eccentric Beaver was soon one of the busiest session men in L.A. He and Krause earned a contract with Warner Brothers . </P> <P> Eric Burdon and the Animals later that same year, in their hit "Monterey", quoted a line from the Byrds' song "Renaissance Fair" ("I think that maybe I'm dreamin"') and mentioned performers the Byrds, Jefferson Airplane, Ravi Shankar, Jimi Hendrix, the Who, Hugh Masekela, Grateful Dead, and the Rolling Stones' Brian Jones ("His Majesty Prince Jones smiled as he moved among the crowd"). The instruments used in the song imitate the styles of these performers . </P>
