Esfahani made his
Wigmore Hall debut in 2009 as a concerto soloist with
The English Concert. Later in 2009, he made his debut at
The Proms in 3 concerts that featured New Generation Artists. In July 2011, Esfahani gave the first solo harpsichord recital in the history of
The Proms, at Cadogan Hall. He returned to The Proms in July 2012, leading the Academy of Ancient Music in his own arrangement of
J.S. Bach's
The Art of Fugue. Outside of the UK, his New York debut was at the Frick Collection in March 2012. Esfahani recorded
Carl Philipp Emanuel Bach's
Württemberg Sonatas for
Hyperion Records, and the recording won a 2014
Gramophone Award in the Baroque Instrumental category. The same recording won him the BBC Music Magazine Award's 'Best Newcomer' award the following year. 2014 also saw Hyperion release his two-disc set of the complete harpsichord works of
Jean-Philippe Rameau. In 2014, Esfahani signed a recording contract with
Deutsche Grammophon (DG), and his first DG recording, 'Time Present and Time Past', was released in 2015. During a 2016 performance of
Steve Reich's
Piano Phase at the
Kölner Philharmonie, some audience members booed, clapped, whistled and shouted 'speak German'. When different factions in the audience yelled each other down, Esfahani stopped the performance and
Concerto Köln and instead played a concerto by
C. P. E. Bach. Some members of the audience apologised for the incident after the concert. On February 11, 2021, Mahan's collaborative album with Danish recorder player Michala Petri and German viola da gamba player Hille Perl, "Bach: 6 Flute Sonatas," won the Danish Music Award P2 Prize for Best Classical Album. ==Personal life==
