Las Instancias comprises Shantala Ferreyra on clarinet, FermÃn Suárez on double bass, and Gonzalo Goicoechea on drums. Ferreyra is an Argentinian clarinettist and composer who graduated from the Jazz Performance Program at the Manuel de Falla Conservatory in 2024. In 2025, she released her debut album featuring her original compositions performed by her quintet, and in 2026, she was awarded a scholarship to study composition in Basel, Switzerland. Her work combines composition and improvisation.
Suárez is a double bass player, improviser, songwriter, and composer from Rosario, Argentina. His artistic work encompasses a wide range of genres, including jazz, tango, Argentine folk, improvised music, and classical, often mixing, stretching, and breaking the limits between languages and traditions. He co-created the punk-tango and avant-garde ensemble ‘La Rompiente’ for which he composes and arranges. In 2026, he started the solo project ‘Ola de sótano’, a double bass and vocals set with electronics, featuring songs, improvisations and spoken word. He’s also a frequent collaborator of composer and pianist RocÃo Giménez López.
Goicoechea is a drummer and educator specializing in jazz. He began his studies at the Leopoldo Marechal School of Arts and later continued at the Manuel de Falla Conservatory. Since 2021, he has performed with a variety of jazz-oriented ensembles.
After a year devoted to live performance and composition, Las Instancias is released by the Argentine label 625 Discos, and captures the result of their ongoing collaboration so far.
With no harmonic instrument, the trio leans into timbre, register, and the register distances between clarinet, bass, and drums. The pared-back format serves as the foundation upon which the group builds its identity and scribes its musical language.
The ensemble work their way through various compositions (mostly written by Ferreyra and Suárez) that constantly flirt with the edges of jazz and improvised music, exploring their aesthetic possibilities and different orchestration combinations.
Recorded during a session in Rosario, the album seeks to become a living reflection of a live performance, with all its nuances and dynamism. There are fierce solos rooted in jazz language contrasted with moments of introspection expressed through a more abstract idiom, all while maintaining a strong sense of tension and attention. There is a sense of a group whose members perform in proximity, without separation or post-production tricks. The recording is an intimate encounter between both the musicians and the listener. The absence of a harmonic instrument becomes a presence: a framework that pushes them toward inventive orchestration, elastic structures, and an exploration of musical language.
This album contains some standout solos and ensemble work. There is a subliminal quality to this trio that makes the music fun, as well as profoundly interesting to listen to. Don’t be fooled by the opening bars of the first track. ‘Lampara Nueva’ starts like a traditional jazz piece, but develops into something extraordinary, the dialogue flowing between the clarinet, bass and percussion like water, flowing back and forth, with a swing here, a change there, and something just for the heck of it anywhere you might care to drop in. There is a taste of traditional jazz, particularly in the drum solos that emerge from the ensemble work, particularly in the second half of the number, but there is also much free playing.
‘Mucho Agora Mismo’ starts with a gentle bass solo and works itself into a frenzy, the clarinet delivering fiery solos across the percussion, with many variations in between. This is a track of many parts, blended seamlessly together. Just beautiful.
‘Dos Veces Agosto’ is a track of harmonies, rhythms, and counter-rhythms, with some bass solos, clarinet that works around the theme, and explores many musical avenues, while maintaining a connection with the central theme. ‘En Meyo’ is a clarinet solo track, with Ferreyra meditating on a theme, while ‘Ok/Off’ is a track where all three instruments lock into the same rhythmic pattern, creating a hypnotic dynamic. A bowed bass emerges, warm and resonant, before the trio returns to their lively, idea‑trading interplay.
‘Pegao’ is introduced by a bowed bass solo, over which the clarinet drops, adding light touches and a rapid change of texture, which the drums enhance, adding their own feel and colour. It is worth listening to this for the changes and rhythmic patterns that evolve, disappear, and re-emerge, led largely by the bass, whose voice is central to this number.
The album closes with a second take of 'Mucho agora mismo' which is extravagant and allows each musician to deliver improvised music of the highest calibre.
Las Instancias are three musicians whose shared curiosity has shaped a sound that feels both stripped back and richly alive. There’s a cohesion that makes the music both fun and deeply absorbing. You hear three musicians who trust each other enough to take risks — to push, to pull, to leave space, to fill it, to let the music breathe and then ignite. It’s intimate, inventive, and full of personality.
