Ariel Eberstein was born in Buenos Aires, Argentina in 1979 and discovered the double bass at the age of 16. In 1997, he began studying the double bass in Buenos Aires with Miguel Angel Villaroel. Thanks to his commitment to this instrument, in 2002, he was granted a scholarship from the Fundación Antochas. Only 4 years after starting the double bass, he continued studying in Vienna with James Rapport (Wiener Kammerorchester) and Andrew Ackerman (Concentus Musicus). Ariel later moved to Belgium in order to continue his studies at the Koninklijk Conservatorium Brussels where he completed his master’s degree, including a one-year Erasmus exchange program at the Koninklijk Conservatorium Den Haag in 2010 with Quirijn van Regteren Altena (Schoemberg Ensemble).
Ariel has worked with many world-famous conductors and has played in the most important Belgian orchestras such as the Vlaamse Opera, National Orchestra of Belgium, De Filharmonie, Orchestre Philharmonique de Liège, Opera Royal de Wallonie, De Munt/La Monnaie and Brussels Philharmonic. He also has given concerts in the most important concert halls of Europe and America, including Concertgebouw and Bimhuis (Amsterdam), Musikverein and Concerthaus (Vienna), Festspielehaus (Salzburg), Cité de la Musique (Paris), Bozar and Flagey (Brussels), Polin (Warschaw), Cadogan Hall (London), The Usher Hall (Edinburgh), Casa de la Musica (Ecuador), Teatro Mayor Santo Domingo (Colombia), Usina del Arte and Teatro Colon (Buenos Aires).
Since 2014, Ariel Eberstein has specialized in tango music and leads the Brussels-based and internationally renowned tango ensemble SONICO (more info below). Thanks to this project, Ariel has become an artist of reference in interpreting music from the "tango vanguardia" period. In July 2018, SONICO went on tour to Argentina to present their first album “EDUARDO ROVIRA: LA OTRA VANGUARDIA” in Buenos Aires as part of the Tango BA Festival, as the main international guest at the festival. In March 2019, the European release of SONICO’s album took place at BOZAR/Palace of Fine Arts in Brussels as the only European group invited to the concert series “100 YEARS OF TANGO.”
In July 2018, Ariel was invited by the well-known Argentine pianist Martha Argerich to participate in the closing concert of her festival in Hamburg. This festival resulted in a triple CD entitled "Rendez-vous with Martha Argerich" on the record label Avantimusic. Eberstein also appeared on the record “Reunion” by Argentine composer and four-time Grammy award winner Fernando Otero, released by Etcetera Records in December 2018. Eberstein then joined Otero's 2018 European tour as a double bassist.
Together with violin virtuoso Michael Guttman, Ariel gives regular performances at various festivals and concert halls: Pietrasanta in Concerto (IT), Odessa Classics (UKR), Queen Elisabeth Music Chapel (BE), etc.
In December 2019, Ariel Eberstein recorded SONICO’s second album “EDUARDO ROVIRA: INEDITO E INCONCLUSO”. During the same year Eberstein participated in the festival “Le Printemps du violon” together with the bandoneonist Olivier Manouri in Paris. He was also invited to the POLIN festival in Warsaw as the artist/curator with a program around the influence of Judaism in the tango.

Since 2018, Ariel has developed a strong artistic relationship with choreographer Lisi Estaras (Monkey Mind/ Les Ballets C de la B). In August 2018, they collaborated on the creation Sapiens Rabia at the San Martin Teatro/Ballet Contemporáneo (Buenos Aires, Argentina).
They continued this collaboration with the creation of D-EFFECT, which premiered at the BUDASCOP (Kortrijk, Belgium) at P-asserelle Kortrijk. Estaras made a dance performance for 3 young dancers, 2 dancers with Down syndrome and Ariel as a double bass player.
Their collaboration, NO HUMAN NO CRY, premiered at the SommerSZENE Festival (Salzburg) at the Bodhi Project dance company (SEAD). In August 2019, Estaras and Eberstein collaborated again on the creation of VERNACULO with the Compania Nacional de Danza Contemporanea de Argentina with its premiere at the Centro Cultural Kirchner.

In May 2019, Ariel Eberstein received an artistic grant from the Flemish Community to collaborate with Lisi Estaras and further explore the relationship between modern tango and contemporary dance during various residencies offered, including Tanzhaus Zurich (CH), SZ Scene Nationale Montbéliard (FR) and Centro per la Scena Contemporanea Bassano del Grappa, (IT).

In 2021 Mr. Eberstein made his first Russian presentation during the “SUMMER EVENINGS IN YELABUGA” directed by Boris Berezovsky. That same year Eberstein, together with SONICO, celebrated the centenary of Astor Piazzolla with the pre-release of his third album, “PIAZZOLLA – ROVIRA: THE EDGE OF TANGO” during the Klara Festival in BOZAR and was hailed as the most watched concert of the whole festival. The official release of ‘Piazzolla-Rovira: The Edge of Tango’, was broadcasted by Film & Arts throughout Latin America.
