the deep tones of the double bass

and the multi-colored sounds of the accordion

create a unique musical journey

about us

Inner Duo was formed in 2020 as an ensemble within Codarts, music Conservatory in Rotterdam and it is made by Helena Sousa Estévez, accordionist from Spain and by Alejandra Rony, double bass player from Costa Rica.

We are both specialized in classical music and we are both interested in all music styles. The beautiful combination of our instruments and our rich cultural backgrounds lead us to create sonic landscapes that traverses classical, world, and modern music.

Inner Duo has performed at various venues and festivals, including the Spiegelzaal in the Concertgebouw in 2022 (Het Zondagmorgen), Muze van Zuid 2022, Dutch International Tango Week 2023, North Sea Round Town 2023, the Rietveld Theater in Delft 2024 and the Hillegonda CrossOver Festival 2024.

We also bring our music to special places: from care centers, where music offers comfort and connection (Muziek in Huis), to children's concerts at SKVR, where accordion and double bass stimulate the imagination of young listeners and open up a magical world of sounds.

Thanks to subsidies from the Performing Arts Fund and Droom en Daad, we were able to develop a varied repertoire, from which two special projects have emerged: Introspective Concerts and Daydream Concerts. At the Introspective Concerts, a carefully selected repertoire of quiet classical music offers the audience a moment of relaxation and reflection. The Daydream Concerts take listeners on an enchanting journey through the rich sounds of world music.

Discover Our music!

our last project “Crossing Classical” brings music from the well known composer Astor Piazzolla to life, alternating with the rich diversity of French and Spanish classical music, and further enriched by Dutch and Latin American rhythms.
