[1][2] Gustavo de Almeida Ribeiro, popularly known as Black Alien, began his career as a rapper invited by fellow MC and musician Speedfreaks, at the time known as Cláudio Marcio.

Before rapping, Gustavo was an amateur skateboarder and even competed in some semi-professional championships, but after pursuing a career in music, his life as a skater was set aside.

At the age of 15, while his friends went to Disney, Gustavo preferred to tour Europe, he went to 8 countries, visited museums, sights and was in contact with different cultures.

Speed Freaks was a group considered ahead of its time, with lyrics sung in English and Portuguese mixed in an uneven rhythm.

That same year, Black Alien participated in the compilation album, No Major Babies, which had the song "Hit Hard Hip Hop" released in Brazil, Europe and the United States.

They then formed the duo Black Alien & Speed, moved to São Paulo and recorded the album Na Face, with guest appearances by Chorão, Herbert Vianna, Xis, Igor Cavalera, Derek Green, Otto, Rodolfo Abrantes and Digão.
