In Paris, Alkan was a member of an accomplished social circle that included many of the leading names of his times in thought and the arts. In 1838, he appeared in concert with his close friend and neighbor, Frederic Chopin, and was warmly received by critics and public alike. To this day there is no definitive explanation of what ensued from this point, though surmise and conjecture aplenty have flourished. For six years Alkan disappeared from the concert stage. He performed again for nearly two years, then dematerialized as a public pianist for 28 more years; when he appeared again he was past 60.
In his time, Alkan was considered the peer of Chopin and Lizst in technique. He is widely thought of as an eccentric par excellence. In his later years he became intrigued with the pedalier, a pedal board that attaches to the piano and enables full performance of organ literature on the piano. He was fond of playing the compositions of Bach on this device and composed copiously for it. His piano works require the utmost of skills, attesting to Alkan's own. Few performers care to attempt the difficulties of the Alkanian oeuvre in public, though some display their uncommon prowess by means of his works. The name of Alkan even now remains one capable of engendering vigorous debate in musical circles. ~ Douglas Purl, Rovi
