ST12 was officially formed on January 20, 2004, although its members had long been in the music world. Earlier, they were not known to each other. They often met in the rental studio on Jl. Stasiun Timur No. 12, near
Bandung railway station. The band was named by Pepep's father, Helmi Aziz. Charly liked jazz, Pepep liked jazz and rock, while Pepeng grew up with rock music. After failing to get a recording contract, ST12 went indie (independent). Their debut album,
Jalan Terbaik, was released in 2006. During the promotional tour in
Semarang, Iman Rush died after a
brain hemorrhage in October 2005. The success of their debut album ST12 caught the attention of Trinity Optima Production. ST12 also released a second album
P.U.S.P.A(2008) in tribute to Iman Rush. In 2012, Indonesian division of
Universal Music Group has reformed ST12 by joining the two new members, Rido Tuah and Koko, as Charly and Pepeng's replacement. In 2014, Dimas Moersas has joined the group as Rido Tuah and Koko's replacement. ==Discography==
