Ayers Rock were an Australian rock band which formed in August 1973. Ray Burton (guitar and vocals), Mark Kennedy (drums), and Duncan McGuire (bass), members of Leo de Castro and Friends, left to form the eponymous trio of Burton, McGuire & Kennedy. They added a guitarist, Jimmy Doyle, changed their name to Ayers Rock and invited Col Loughnan (saxophones and flutes) to join. The group signed with independent label Mushroom Records in December 1973. Burton left the following March, and was replaced by Chris Brown (guitar, vocals). With live appearances, coverage in print media and word of mouth the group had a high national profile despite little radio airplay, and journalists praised their musicianship, music, and live energy.
The band’s first album, Big Red Rock (November 1974), received positive reviews and peaked at number 32 on the Australian Kent Music Report album chart. It featured mainstream rock and three longer, instrumental tracks which introduced progressive styles, including jazz fusion. Label owner Michael Gudinski promoted Ayers Rock in Los Angeles and they signed with A&M Records, the first Mushroom Records artists to sign with an international label. The United States release of Big Red Rock in February 1975 was followed by a tour there, later that year. The band played to large crowds, supporting major international artists (including Bachman–Turner Overdrive) before 35,000 people – the first Australian band to perform in large US stadiums. Ayers Rock were named 1975 Musicians of the Year on RAMs ‘New Year’s Honors List’. Kennedy left before their second album, Beyond (April 1976, recorded at the Record Plant in Los Angeles), was released. The album blended a number of music genres and had a positive critical reception, charting at number 50. The band toured the US again; Loughnan remained there, and Ayers Rock temporarily broke up in August 1976.
