Announced at the beginning of 2017, the Mozartists are an offshoot of Classical Opera, an ensemble formed by conductor Ian Page to explore the operatic world of Mozart and his contemporaries. The Mozartists have the intention of adding instrumental music to the company's capabilities, and it has been closely associated with Page's ongoing Mozart 250 project, aimed at recording a wide swath of music by Mozart and other composers in his orbit. The Mozartists got its recording career off to a fast start, releasing Perfido!, a collection of operatic rarities by Haydn, Mozart, and Beethoven with soprano Sophie Bevan, in 2017. In 2021, the group issued recordings of Arne's Artaxerxes and Niccolò Jommelli's Il Vologeso.
