Who played piano on the Confessions II track Betrayal?

Kamilla Arku played piano on the Confessions II track “Betrayal.” Her contribution is specifically listed in the song’s official credits, alongside keyboards by Madonna, Stuart Price, Mirwais and Marco Parisi.

“Betrayal” is one of the album’s more musically referential tracks. Its writing credits include French composer Erik Satie, and the song uses material from Satie’s “Gnossienne No. 1,” a composition first written in 1893. Arku’s piano performance helps connect that older, spare piano language with the album’s modern electronic production.

The track was produced by Madonna, Stuart Price and Mirwais, with additional production by PARISI. Price also handled bass and string arrangement, while Mirwais contributed to drum programming and production. Those credits explain why several other names can look plausible in a multiple-choice question.

Kamilla Arku is not the producer or principal keyboardist on the song; the precise credit is piano. Laura Sisk, Lauren D’Elia and Lanita Smith are associated with engineering or other Confessions II production credits rather than this piano part.
