Move over, John McCain and Sarah Palin. The “maverick organist” — as The New York Times dubbed Cameron Carpenter — is about to blow out the pipes at Royce Hall in an evening titled “Revolutionary.” Taken from the title of Carpenter's new Telarc CD, the program includes all sorts of wild departures from the traditional organ repertoire, including feats — or should we call them feets — of the almost impossible, such as a transcription of that Chopin endurance test, the “Revolutionary” Etude, in which Carpenter plays the right-hand part on the keys and the left-hand part solely with his feet. Also on the program: French modernist Jeanne Demessiuex’s “nearly unplayable” Etude in Octaves; an organ version of Liszt's fiendish Mephisto Waltz; and Carpenter's own evolutionary Toccata and Fugue in D minor, an “outrageous survey of the various instrumental arrangements that made Bach's piece famous.” UCLA, Royce Hall; Sun., Oct. 26, 7 p.m.; $15-$32.
