With Manel Cruz (vocals), Nuno Prata (bass), Peixe (guitar), Kinörm (drums) and Elísio Donas (keyboard) and only two albums, they quickly became a reference in Portuguese music of the end of the 1990s, though the most successful part of their career lasted for only three years, after which the group split.
In 1997, they composed Cão! (Dog!) their first album - which included the song Letra S, a duet with Manuela Azevedo, the voice of Clã (another successful Portuguese band) - an album where for the first time the group showed they were keen to explore a mixed sound, with Cruz's unique writing style, much to their fans', and most of the national musical reviewers', delight. In the following year, during the Expo 98, they collaborated on the compilation Tejo Beat alongside Boss AC, Blasted Mechanism, Zen and Flood with the song Tempo de Nascer.
Their last album, O Monstro Precisa de Amigos (The Monster Needs Friends), came out in 1999, with a more carefully thought production, and generally speaking, a less active and calmer style. The album contained the singles Ouvi Dizer, a duet with the older Portuguese musician Vitor Espadinha, and Capitão Romance, with Gordon Gano, vocalist of the well-known Violent Femmes. It was also during that year that they helped to produce XX Anos XX Bandas, a tribute to the Portuguese band Xutos e Pontapés, with a cover of Xutos' song Circo de Feras.
After some speculation about their future, Ornatos Violeta split up in 2002. Pluto followed, a more traditional rock group, with Manel Cruz (vocals + rhythm guitar) and Peixe (lead guitar).
In 2009 one of the main radio stations in Portugal, Antena 3, celebrated 15 years choosing the best 15 albums of those years. O Monstro Precisa de Amigos came in 1st place.
In 2012, the band performed seven shows, which were announced as being their last. The first was in the Paredes de Coura Festival, three shows in the Coliseu dos Recreios (Lisbon), three shows in the Coliseu do Porto and one show in the Coliseu Micaelense (Azores).
