Maria Cristina Ozzetti was born in Sao Paulo, on December 12th, 1958. At the age of four, her youngest sister gave her the nickname 'Ná'. Ná came from a family that greatly appreciated the arts. During her childhood, she and her siblings all played musical instruments, Ná focusing on piano and singing.

Ná's earliest professional experience was as the singer in her brother Dante's band. She was fifteen when they first performed at a school festival. Since then, singing has been an integral part of her life.At the age of seventeen, Ná attended university as an Art major but never gave up her pursuit of music. She took her first singing lessons at the age of nineteen with the American instructor Lee Alison.

In 1979, at the age of 21, Ná began her professional career as a member of Grupo Rumo. Over the course of eleven years she recorded six albums and appeared in countless live performances with this group. At the age of twenty-two she began singing lessons with Claudia Mocchi, with whom she studied for ten years. In that same year, she began to take dancing lessons with Klauss Vianna. She soon discovered her passion for dance, which led to studies with Denilto Gomes, Ivaldo Bertazzo, Patricia Noronha, Adriana Grechi, and others.

In 1983 she began her solo career, marked by a solid musical partnership with her brother Dante that continues to this day.While maintaining her solo career and her work with Grupo Rumo, Ná got involved in other musical projects, such as “Princesa Encantada” (Princess Charming) in 1986 with the singer Suzana Salles.

In 1988, she released “NÁ OZZETTI”, her first solo recording. This project was awarded the prestigious Sharp Award and Lei Sarney Best New Talent Female Singer Award. In the same year, she was invited by Itamar Assumpção to perform in Germany, Austria and Holland. One year later, she and José Miguel Wisnik starred a concert performing songs he had written.

In 1994, Ná released the CD “NÁ”, celebrating her debut as a composer. This album was awarded two Sharp Awards, as best Pop/Rock Album, and “Best Arranger” (for Dante Ozzetti). During this period she also worked with the architects Isay Weinfeld and Marcio Kogan who designed the scenery for her concerts.

1996 marked the release of the CD LOVE LEE RITA on the Dabliú label. On this recording, Ná pays homage to the singer and composer Rita Lee. In 1997/98, Ná participated in many projects, most notably the highly acclaimed concert “Ná canta o Brasil” (Ná sings Brazil), directed by Eugênia Thereza de Andrade.

In 1999, Ná created her own record label, NÁ RECORDS, and released her fourth solo album, ESTOPIM. This CD brings a collection of original material written in collaboration with Dante Ozzetti. The project also features Luiz Tatit, Jose Miguel Wisnik, and Itamar Assumpcao.

In 2000, Ná was awarded Best Female Performer at the Brazilian Music Festival promoted by Rede Globo (TV Station) for her performance of the song 'Show', written by Luiz Tatit and Fábio Tagliaferri. The award resulted in the release of the CD “SHOW” on the Som Livre label, on which Ná performs sambas from the forties and fifties by such legendary Brazilian composers as Dorival Caymmi, Herivelto Martins, Maysa, Ari Barroso, Tom Jobim, among others. During the following years, Ná performed numerous times in Brazil and abroad.

In 2004, Ná initiated a new project with Dante Ozzetti, Mário Manga and Sergio Reze, a work that will soon be recorded and released as a new CD. Later that same year, Ná accepted an invitation from the composer/arranger/pianist André Mehmari to take part in the project 'Piano and Voice' at the Federal University of Rio Grande do Sul. Acclaimed by public and critics alike, the project resulted in the release of the Duo CD called ‘Piano e Voz’.

Along with her solo work, Ná Ozzetti's talents have led to invitations to participate in the projects of many other artists.
