He regularly performs an extensive part of the classical repertoire, and feels the need to explore forgotten masterpieces, by famous and unknown composers alike. This has led him to adore the explosion of musical expressions, languages, aesthetics in the earlier part of the 20th century. A keen interpreter of contemporary music and a staunch supporter for new music, he has given numerous first performances of solo and ensemble works. Orlando attended the CNSM in Paris, where he studied piano (Roger Muraro), chamber music (Itamar Golan), collaborative piano (Jean-Frédéric Neuburger) and composition (Thierry Escaich). He is pursuing an artist diploma at the Hochschule für Musik Hanns Eisler in Berlin with Kirill Gerstein.

A disc of Preludes and Fugues for solo piano, spanning the 20th and 21st centuries, was released in 2018 by Indésens, and a solo double disc featuring both his own compositions and some by Olivier Penard was published by Dux in 2021. Other discs as a chamber musician or as a composer are published by Odradek, Paladino media, Triton, Hortus, Maguelone and Paraty. Orlando Bass is a laureate of the Fondation Banque Populaire, which actively supports him in his diverse and varied projects, both as a performer and composer.
