[10] Following his recital in the Queen Elizabeth Hall a year later, the same critic described Papadopoulos in The New Grove Dictionary of Music and Musicians (1975 edition) as having “all the attributes of one of the world’s greatest players”.

A fourth complete cycle of the symphonies and concertos as part of the 2020 Oxford Beethoven Festival to celebrate the composer's 250th anniversary was cut short due to the COVID-19 pandemic.

In March 2018, Papadopoulos appeared with the Guangzhou Symphony Orchestra at the Xinghai Concert Hall in China, directing Mozart Piano Concertos from the keyboard.

[1][2][3] In 2018, he conducted a new production of “The Marriage of Figaro” for the Greek National Opera at the Stavros Niarchos Foundation Cultural Center in Athens.

[12] A prolific recording artist, Papadopoulos's catalogue includes his Beethoven sonatas, performances of Stravinsky's Concerto for Piano and Wind with the Royal Philharmonic Orchestra (Hyperion), works by Mozart, Mussorgsky, César Franck and the twenty-four Preludes and Fugues by Shostakovich.

As a pianist, he and Maxim Vengerov have recorded the complete Brahms violin sonatas and performed these in a recital at Vienna's Musikverein in September 2016.
