Altera Inde
Committed to creativity and creation, the artistic project Altera Inde develops in the contemporary music scene. Founded by Sara Zazo and Diego Carretero, they maintain the idea of collaborating with today's composers and developing new works, Altera Inde expands the repertoire for saxophone duo repertoire and enhances the different artistic expressions of our time. With a career spanning over a decade, the duo has performed at prominent festivals and venues across Europe, establishing itself as a benchmark in the performance of contemporary music.
Their journey began in 2013 with a high-impact educational project in Extremadura (Spain); their teaching efforts helped foster a new generation of saxophonists by introducing contemporary musical language into instrumental practice from an early stage. This educational drive soon evolved into an artistic career that has led to the premieres of more than twenty works by renowned composers—such as G. Lorusso, G. Navarro, S. Movio, I. Badalo, and D. Sprintz—along with performances in France, Spain, Romania, Germany, England, and Switzerland.
In 2019, they released their debut studio album, HIRAETH, a collection of acoustic works for saxophone duo that was enthusiastically received by music critics. Since then, Altera Inde has focused its artistic research on the symbiosis between the saxophone and electronics, thereby expanding the duo's expressive horizons.
Recent highlights include their 2025 appearances at events such as the Badajoz Contemporary Music Festival, the 27th Contemporary Music Series at the Vostell Museum, and the Meridian Festival in Bucharest, reaffirming their commitment to living creation and dialogue with the artistic languages of the present day.
In June 2026, they undertook the DOUBLE SKIN tour across three Swiss cities (Bern, Basel, and Lausanne). In September 2026, they will make their debut at the Musikwerkstatt Alte Schmiede series in Vienna, continuing their commitment to a musical practice that is socially engaged, boundary-pushing, and in a state of constant evolution.
