Everything began in a meeting in 1982 when a band called Bandeira Rasgada came out. Eduardo Miranda (guitar), Nelson Sanchez (voice), Jorge Sanchez (bass), and Vladimir Augusto (drums) started playing hard rock music. Later, with keyboards, Nelson Sanchez and Henrique Valsésia (voice and saxophone) started to make new songs with elaborate arrangements; they then decided to change the band's name to Última Geração.
After some time, another new name emerged: Renascença. With this name, the group became known in São Paulo's underground and entered the studio to record two songs, which got the support of important musical critics.
In 1986, Nelson Sanchez left the band and Alessandro Miranda took his place. The band presented some gigs in São Paulo. In this time, they released their first album, called Renascença, with special guest Amir Cantúsio Jr. from Alpha III. From this time, the band started to be called Wejah.
After this record, the band broke up. In the middle of 1991, Miranda and Augusto re-formed the band with Jorge Sanchez and Celso Santos, composing a new experimental sound, but it didn't last. Together again, Miranda, Jorge Sanchez, and Augusto, with Marcelo Perez (keyboards) and Maurício Freitas (voice), performed some shows in 1993, but this lineup didn't last either. Augusto left the band and Alexandre Crescenzi took his place.
At the beginning of 1995, Freitas left the band and Wejah decided on instrumental music. At the end of that year, Wejah showed a new sound inspired by a work called "Senda" (Narrow Road) and recorded the CD Senda.
