The Jones Maruri duo is the only established cello guitar duo in the world and enjoys an active concert and recording career.

Formed in Madrid in 1990, Michael Jones and Agustin Maruri have since played concerts in Europe, the Americas, Asia and Australia. Their first US tour was in 1991 and included concerts in New York and St Augustine. Since then they have performed each year in the United States, giving recitals in New York, Chicago, Houston, Washington DC, Los Angeles and San Francisco, at venues such as the Lincoln Centre, Metropolitan Museum of Art, the Hancock Centre and at festivals in the US, Cuba and Venezuela.

The duo has investigated the original historic repertoire for their combination. Agustin Maruri has received scholarships and awards as a result of, and towards, his work as a musicologist, discovering many lost or forgotten works in the Biblioteca Nacional de Madrid, the Munich Library and the British Museum. Their discography includes the first recording in the world of original compositions from the 19th century for cello and guitar, including music by Leonhard von Call, Thomas Matiegka and Friedrich Dotzauer. They have also recorded most of the original repertoire of the 20th century for this combination and have inspired living composers to write for them such as Pedro Saenz, Francesco Telli, Erik Marchelie, Nicholas Marshall, Jose Maria Sanchez Verdu, Drew Hemenger, Paul Coles and Satoshi Tanaka.

Their recording “Original Music for Cello and Guitar” was a top ten in the classical market in Hong Kong for one year. Due to this success in East Asia, they were invited to record a CD of traditional Chinese melodies for the Taiwanese record label Maysun.

In 1999 Jones and Maruri recorded for the Metropolitan Museum of Art in New York '”The Charm of Spain”, a collection of Spanish romantic melodies from the 19th century performing on instruments from the museum's collection.

In 2004 they released their latest recording together “Don Quijote y Dulcinea” and toured North America and the Middle East.

Following their debut tour of Japan and the Far East in July 2007, the duo has been invited to perform at the 2008 Beijing Olympics, playing concerts in the Forbidden City concert hall, as well as Shanghai and other cities in the People’s Republic
