In 1993, CANTO NONO organized and participated in two seminars with Ward Swingle, founder of the Swingle Singers in the 1960s.

The work done with this musician was crucial for the octet's evolution, and they continue to include works by Ward Swingle in their repertoire, some of which were specifically arranged for CANTO NONO.

Following this work, CANTO NONO's first discographic recording was published by the newspaper "Público" and commercially released in May 1997.

In 1998, the first track from this CD, "El Paisanito," was nominated for a best performance award in the "Folk/World Music" category by CASA (Contemporary A Cappella Society of America), an American association that brings together vocal groups from around the world. This track was also included in a compilation of the best a cappella music recordings from that same year, featuring other names such as The King's Singers, The Bobs, and The Concordia Choir.

Diverse musical experiences led the group to record the soundtrack composed by Jorge Constante Pereira for «Furnas/Uma visita» (Furnas/A Visit), an installation by Ângelo de Sousa;

To provide the vocal support for the street performance «Queima do Judas» (Burning of Judas), organized by the Porto City Council;

CANTO NONO's repertoire is traditionally a cappella.
