Mauro Juliany Cogo began to study music at the age of fourteen. He started on the guitar with Wesley César. Later, he studied with Mozart Mello, Faíska, Wander Taffo, Claudio Celso and others from the earliest generation of São Paulo's IGT (Institute of Guitar And Technology). He then achieved an advanced level with Aldo Landi, with whom Cogo studied improvisation, jazz, MPB (Brazilian Popular Music) and initiated his courses of arrangement and orchestration. He completed these studies later with Frederico Zimmermann Aranha. During more than ten years of regular musical practice, Mauro Juliany Cogo also took singing lessons with Regina Carvalho and Nancy Miranda. At the Cameratti school, where he taught, he had percussion classes with Formiga. Throughout this period, he gave his first steps in the world of audio, recording and producing his bands. In 1997, he enlarged this experience at the Cia de Áudio, a mastering studio. Afterwards, Cogo was co-founder of Alchimia, a music studio of which he was partner for five years. There, he produced and recorded rock and metal bands that achieved considerable repercussion, such as Panzer, Tomada, Assédio Social, Scars, Nau Capitânia, Andrômeda, O Uivo and Chasing Fear. Today, he has his own production infra-structure with the Soundup studio. Multi-instrumentalist and virtuous guitarist, Mauro Juliany Cogo has been a music teacher since 1993. He made soundtracks for television series like Turma do Gueto, from Record TV. Composer of different styles, Cogo makes his way easily from MPB to the Blues. His strongest references, however, are the classic hard-rock and metal bands, including guitar players such as Tony Iommi, Yngwie Malmsteen, Zack Wild e Richie Blackmore. Even having worked with production for nearly ten years, Cogo is only now releasing his first official CD. This work is the materialization of an idea triggered by Cogo's former band C.O.X. From this experimental period came the inspiration for the actual CD, named The Battle. The initial workshop with the album riffs was recorded in the beginning of 2003. Two test songs were produced: Day of Fighting (that achieved it's fourth version on the CD) and Sail Away, by Deep Purple. Since then, many experiments were carried out: tone tests, instruments, everything had to sound unique. "I wanted to have the essence of the classic metal from the 70's and the 80's, with the heaviness and modernity of the last decade", explains Juliany. Meanwhile, influences of bands like Prodigy, Stuck Mojo, Marilyn Mason and Rage Against the Machine - that add to metal shades of funk and eletronic beats - were being distilled. It was the search for the sonority and the beginning of The Battle. "And this will be the first one, because the war never ends", says Mauro Juliany Cogo.
