His 1973 hit " Terajana", one of the best-known dangdut songs of all time, was the first to use the newly coined, and arguably derogatory, term dangdut, distinguishing the Javanese Orkes Melayu music, heavily influenced by Indian Bollywood records, henceforth dangdut, from the established Orkes Melayu, associated with North Sumatran Malays. Furthermore, the main single "Begadang" reached at number 24 on the magazine's " 150 Greatest Indonesian Songs of All Time" list. 11 on Rolling Stone Indonesia 's " 150 Greatest Indonesian Albums of All Time" list.

His choice of pose showed the influence on his music of Western bands, influences which also found their way into his music – Orkes Melayu was in his opinion was too soft, too acoustic, too polite, and unable to compete against the power and energy of rock music, and so the music was electrified, with keyboard, two electric guitars, electric bass, as well as the traditional suling and gendang.

Their first album, Volume 01, Begadang ("Stay up all night"), released in 1973, featured four songs by Oma Irama, three by Elvy, and three duets.

He also recorded pop Indonesian music during this period with the Zaenal Combo and Galaksi, while the album Ingkar Janji was recorded in 1969 with Orkes Melayu Chandraleka. This group pioneered elements of the dangdut style within Orkes Melayu music – the drum was changed to double drum, the electric guitar's role was expanded, and the suling, or bamboo flute, adopted a style reminiscent of Bollywood music. In 1968 he joined the group Orkes Melayu Purnama in 1968. In the late 1960s Oma Irama, sang jawa and also some pop Indonesia music.
