Trio Bintang were from Indonesia.
The Republic of Indonesia, is a nation in Southeast Asia. Comprising of 17,508 islands, it is the world’s largest archipelagic state. It is also one of fourteen nations that the Equator runs through. With a population of almost two and a quarter million people, it is the world’s fourth most populous country and the most populous Muslim-majority nation, although officially it is not an Islamic state.
During the early 1960s, President Sukarno was under pressure from the pro-communist organization Lembaga Kebudayaan Rakyat to ban rock’n’roll. Local groups rock groups were often thrown in jail. Due to this fact, one of Indonesia’s first rock bands, Koes Bersaudara had a hit with a song called “I’m In Jail”, which was also included on their first album.
The only information that I have been able to find about Trio Bintang, is that their guitarist was Jopie Reinhard Item. He apparently had also performed with Lilis Suryani, Elly Kasim, Titiek Puspa, Ernie Djohan – to name a few. He now plays instrumental jazz. And apparently, Trio Bintang performed for a reunion show in 1999 for the Wisma Anak-Anak Harapan orphanage in Untal-Untal Dalung on the island of Bali.
