He was educated at the Moscow Conservatory in the class of Professor Mikhail Petukhov, and at the Lake Como International Piano Academy in Italy.

Masleev has performed in such countries as Russia, Japan, US, Italy, China, and England, and has collaborated with such conductors as Valery Gergiev and Yevgeny Svetlanov.

In January 2017, Carnegie Hall presented Masleev's highly anticipated debut at the Isaac Stern Auditorium with a recital programme featuring works by Scarlatti, Beethoven, Liszt, Rachmaninoff and Prokofiev.

In his first touring season Masleev made a series of successful debuts, establishing his world-wide audience and developing his profile as a "future great pianist" (La Croix[2]) of "virtuoso brilliance" (The Financial Times), "musicality of metaphysical proportions" (Neue Musikzeitung[3]), "discovery of a new and real talent" (Classic Toulouse[4]), portraying "wonderfully fragrant landscapes" (Aachener Zeitung[5]) whilst "cleverly breaking down sound levels" (Utmisol[6]).

Amongst the most notable performances are those at the Klavierfestival Ruhr, with the Munich Philharmonic am Gasteig in Munich, la Roque-d'Anthéron and Bergamo & Brescia piano festivals, two tours of Japan with Valery Gergiev and Yuri Bashmet, the French debut with Orchestre national du Capitole de Toulouse, the opening gala of the Istanbul Festival, as well as the last-minute replacement for the indisposed Maurizio Pollini in Basel.
