This new line-up continued into 1974. The band played at the famous California Jam festival in the Ontario Motor Speedway located in Ontario, California on 6 April 1974. Attracting over 300,000 fans, the festival also included 1970s rock giants Black Sabbath, Eagles, Emerson, Lake & Palmer, Earth, Wind & Fire, Seals and Crofts, Rare Earth and Black Oak Arkansas. Portions of the show were telecast on ABC Television in the US, exposing the band to a wider audience. This lineup's first album, titled Burn, was a highly successful release (only the second album, after Machine Head, to crack the USA Top 10), and was followed by another world tour. Hughes and Coverdale added vocal harmonies and elements of funk and blues, respectively, to the band's music, a sound that was even more apparent on the late 1974 release Stormbringer. Besides the title track, the album had a number of songs that received much radio play, such as "Lady Double Dealer", "The Gypsy" and "Soldier Of Fortune".
