Mutations is a studio album by American jazz pianist Vijay Iyer recorded in September 2013 and released on ECM the following year.

The titular suite features a string quartet consisting of violinists Michi Wiancko and Miranda Cuckson, violist Kyle Armbrust, and cellist Kivie Cahn-Lipman.

"[2] Writing for All About Jazz, John Kelman said "Mutations is a landmark recording from an artist who, while already possessing an admirable discography, has clearly been limited to more decidedly jazz-oriented concerns.

Representing a significant musical shift, if Mutations is but the first sign of the greater freedom ECM plans to afford Iyer, the only vaticinator of what's to follow will surely be its complete and utter unpredictability.

While his previous releases showcased a supremely talented pianist, it appears that signing with the Munich based label opened a number of doors creatively for him.
