In June 2014 Samuel was a prizewinner at the prestigious Evgeny Svetlanov International Conducting Competition in Paris, where he conducted the Orchestre Philharmonique de Radio France at the Salle Pleyel and was described by a jury member as "unfailingly musical." Later that year he led the Roman River Festival Orchestra in Stravinsky's The Firebird suite (1919) and Elgar's Cello Concerto with the LSO's principal cellist Rebecca Gilliver. Other highlights have included: Schumann's Concert Piece for Four Horns with the horns of the BBC Symphony Orchestra; both Strauss Horn Concertos with the Philharmonia's principal horn Katy Woolley; three world premiers; and further music by Beethoven, Borodin, Brahms, Corelli, Dvorak, Elgar, Finzi, Giazotto, Haydn, Mendelssohn, Mozart, Poulenc, Shostakovich, Sibelius, Tchaikovsky, Vaughan Williams and Wagner.
In November 2015 Samuel will make his Russian debut with the Tatarstan National Symphony Orchestra with works by Shostakovich, Korngold and Bartok. In March 2016 he will conduct the Ernest Read Symphony Orchestra with works by Copland, Holst, Webern and Elgar.
