In 1991, Angra was formed, and with the first album, Angels Cry, released in 1993, the band became famous in Japan and Europe.

Angra's style evolved from a Helloween-inspired melodic speed metal to a unique blend of heavy-metal, classical music and traditional Brazilian influences which brought them worldwide critical praise.

In 2000, Matos left Angra alongside Luis Mariutti (bass) and Ricardo Confessori (drums) because of a disagreement with guitar players Rafael Bittencourt and Kiko Loureiro concerning the band's management.

The band was a sudden success due to the song "Fairy Tale" which was featured in the Brazilian soap opera Beijo do Vampiro (Vampire Kiss).

Their second release, Reason, kept the fame and culminated in a concert in front of 10,000 people in Rio de Janeiro.

Besides all success heading the release of the album and the expectation over the album, Matos decided not to record any worldwide video clips; he only recorded and released an exclusive video clip for the Japanese audience which features a cover.

Mentalize was released in Brasil and Japan first, at the end of 2009, and a tour started in Brazil, with concerts in Rio de Janeiro, Recife, São Paulo, Fortaleza, and some other cities.

In November 2010, Matos joined Symfonia, a power metal supergroup formed in with Timo Tolkki, Uli Kusch, Jari Kainulainen, and Mikko Härkin.

After that, the solo band and Viper joined each other on the secondary stage of the biggest Brazilian festival, Rock in Rio, for a special concert and opening act for Helloween and Iron Maiden.

The death was announced by a note published on social networks and signed by the members of the band Shaman.

As a wish manifested in his life, there was no public wake and the singer's body was cremated in an undisclosed location.
