The band was formed in 1984 by Anoorak "Tui" Yingnakorn (ตุ้ย: อนุรักษ์ ยิ่งนคร) and Seree "Max" Vihokhern (แม็ก: เสรี วิหคเหิน) and brought together musicians to add more.
Later, when the lead vocalist has resigned, the band has Surush "Pe" Tubwang (เป้: สุรัช ทับวัง) backed up.
Later they signed with RS Promotion with the persuasion of the scout Thanapol "Suea" Intharit (เสือ: ธนพล อินทฤทธิ์).
Hi-Rock achieved immediate success with the release of their first studio album Khon Pan Rock in 1990, dressed in a colorful costume, eye makeup, inspired by Cinderella and Loudness.
Before Tubwang quit in 1997, the band changed name to HIROCKSHIMA and replaced the new lead vocalist.
