Anton Rubinstein (1829-1894) was an outstanding personality in 19th century music: a virtuoso pianist, conductor, composer and pedagogue whose influence extended far beyond his own works. Born in Russia, Rubinstein achieved international fame as a pianist of almost legendary ability, rivaled only by Franz Liszt. He was instrumental in establishing a Russian music school and founded the St. Petersburg Conservatory in 1862, where he trained a new generation of composers and performers.

As a composer, Rubinstein was extraordinarily prolific, writing symphonies, operas, chamber music and countless piano works. Although his style is rooted in German Romanticism, particularly Mendelssohn and Schumann, Rubinstein's music often reflects his own expressive temperament, with a combination of lyrical expressiveness and dramatic force. The two cello sonatas occupy a special place among his chamber music works. The Cello Sonata No. 1 in D major, op. 18 (1852), reflects Rubinstein's youthful energy and lyricism. The three-movement work demonstrates both the tonal qualities of the cello and the virtuosity of the pianist.

The composition is warm-hearted, charming and infused with sublime romantic melodies, although some critics have emphasized its more traditional, German-influenced character. Nevertheless, it demonstrates Rubinstein's talent for soulful, expressive music that gave the performers room to develop. More ambitious is the Cello Sonata No. 2 in G minor, op. 39 (1857), which was composed only five years later but reveals greater maturity and depth. The four-movement work has a broader thematic framework and a darker, more dramatic character. The interplay between cello and piano is more complex and the instruments are treated as equal partners. Its passionate themes, stormy climaxes and lyrical slow movement make it a particularly captivating work that is often considered Rubinstein's most important chamber music composition.

Although Rubinstein's cello sonatas are no longer performed as frequently as works by Brahms or Chopin, they remain valuable contributions to the Romantic repertoire and provide an insight into the artistry of a composer who combined Russian and European traditions. Played with passion and delicacy by Matilda Colliard (cello) and Stefano Ligoratti (piano).
