"Rubinstein's Second Piano Trio was also published in 1855 at the same time as the First. The lilting main theme of the opening Moderato is indeed quite effective while the development section, which leads to the delightful, lyrical second theme, is very finely done. The magnificent second movement, Adagio, is a gorgeous Mendelssohnian Song Without Words. The Allegro assai scherzo which follows is in the form of a tarantella. This is a lively, fleet and very effective movement. Both melodies of the finale, Moderato, are expressive and well done. This trio deserves a place of honor in the concert hall."
—Wilhelm Altmann writing in his Handbook for Piano Trio Players.
Rubinstein was one of those rare concert virtuosi whose contribution to music went far beyond performing. In 1862, he founded the St. Petersburg Conservatory and served as its first director. His efforts in developing Russian musical talent were perhaps the greatest of any single individual. Not only did he introduce European educational methods but he also established standards that were as rigorous as any conservatory in Europe.
Rubinstein was a prolific composer writing in nearly every genre. Chamber music figures prominently amongst his works. He wrote 10 string quartets, at least 5 piano trios, a string quintet and a string sextet as well as several instrumental sonatas.
