Born in 1994 in Barañáin (Navarra), Iñigo started learning accordion in the local Music School with Mª Antonia González. Following a growing musical interest, he did his Professional Degree studies in Pamplona with Salvador Parada and gained in 2015 his Bachelor Degree in Music with Honours from the Superior Conservatory of Music of Navarra, with Professor Nekane Iturrioz, obtaining an "End of Degree" award.

In 2017 he completed his Master of Arts and, a year later, an Advanced Diploma degree, both at the Royal Academy of Music in London under Professor Owen Murray.

He has assisted various courses and masterclasses taught by renowned accordionists and musicians from other disciplines including Friedrich Lips, Matti Rantanen, Magnus Lindberg, Claudio Jacomucci, Mie Miki, Miguel Ituarte, Alexey Artemyev, Javier López Jaso and Javier Colina.

He has taken part in concerts and festivals in different European countries, such as Spain, France, the Netherlands, Italy and, especially, the United Kingdom. Those performances include the BBC Proms, Adelburgh, Froome and Spitafields festivals (UK), and concert halls of great importance in the music scene, like the Royal Festival Hall, the Elgar Room of the Royal Albert Hall, Wigmore Hall, St. Martin-in-the-Fields, the Union Chapel, St. James's Piccadilly (London), St David's Hall (Cardiff), Glyndebourne Opera House, Colston Hall (Bristol), Grand Theatre (Leeds) and Shakespeare's Rose Theatre (York). Among the instrumental ensembles he has played with are the Philharmonia Orchestra (under Vladimir Ashkenazy), BBC Scottish Symphony Orchestra, Opera North and Glyndebourne Youth Opera.

Iñigo is an active promoter of the accordion as an instrument of great versatility and multiple possibilities, getting involved in collaborations with several contemporary composers. That work has led to the première of new works for solo accordion, chamber music (with different ensembles and instruments) and accordion and orchestra, highlighting the performance of two new accordion concertos as a soloist. He has also been appointed "Park Lane Group young artist".

As a chamber musician, he is member of the Diphonon Duo, along with Greek violist Michael Iskas and the Duo Giuliano-Mikeleiz with Canadian cellist Daryl Giuliano. He also performs with "Unicorn Frequency", a six piece band led by Romanian violinist Bogdan Vacarescu that plays Eastern-European music mixed with classical and jazz styles.

Iñigo has taken part in a long term collaborative project with storyteller Sef Townsend, The Pongo's Dream, a journey through the stories and music of indigenous people from South America.

Regarding the socio-educative aspect of music, as Diphonon Duo, they were appointed Wigmore Hall Learning Ensemble Fellows in 2017-18, being usual collaborators in their projects since then, as well as being part of Live Music Now and Concordia Foundation.
