Born in the outskirts of São Paulo, Brazil, Marcus graduated from the Royal Northern College of Music with a First Class Honours and Masters with Distinction in 2023, studying with renowned double bassist, Jiří Hudec. Straight out of college, he was appointed as one of Manchester Camerata’s 360 Fellows, working across the organisation in both performance and community contexts.

A member of the Latin Grammy's Recording Academy, Marcus has been awarded several prestigious prizes, including the ABRSM Queen's Platinum Jubilee Award and the RNCM Concerto Competition, for which he is the first Latin-American double bass prize-winner in the competition's history.

In 2023, Marcus became the first Brazilian double bassist to perform a concerto with the BBC Philharmonic, marking his professional debut as a soloist in the UK, performing the British premiere of Andrés Martin's Double Bass Concerto No. 1. This season, Marcus has been appointed as the first Artist of the “Soloist Project”, sponsored by Heppleston Double Basses, which has kept him active and enthusiastic as a soloist. This year, he made his recital debut in London as part of the Soloist Project in March, and in August, Marcus will make his first appearance as solo artist for the Edinburgh Fringe Festival.

Marcus frequently works with ensembles as tutti and principal double bass, including the BBC Philharmonic, Opera North, Scottish Chamber, Hallé and Royal Philharmonic orchestras. He has performed with orchestras at some of the most iconic venues across the globe, such as the Royal Albert Hall, Wigmore Hall, Concertgebouw Amsterdam, Elbphilharmonie, KKL Luzern, Usher Hall, Frankfurt Alte Oper and Berlin Konzerthaus.

Marcus' passion is to bring Brazilian music to a wider audience, as well as to change the perception of the double bass in western classical music, bringing it to the fore in concerto and chamber music contexts. As a result of this, he founded and directs the award-winning Brasis Ensemble. Based in Manchester and currently in the format of a Double Bass Quartet, the group was awarded first place in the RNCM’s Elias Prize last year, in their first time ever entering a competition.
