Lady Gaga and Tony Bennett's Cheek To Cheek was released in September 2014 and instantly secured its place as a favorite of fans and critics alike, debuting at #1 on the Billboard 200, Jazz Albums, and Traditional Jazz Albums charts. The astounding musical collaboration pays homage to tunes from the Great American Songbook composed by jazz LEGENDS like George Gershwin, Cole Porter,Jerome Kern, and Irving Berlin.

Some of these timeless songs include "But Beautiful," "I Won't Dance," "Nature Boy," "Anything Goes," and "I Can't Give You Anything but Love." The record has been praised for effectively highlighting the chemistry between the two artists, who span 60 years in age. Its unprecedented success makes Bennett the oldest artist to have a #1 album on the Billboard charts and marks Lady Gaga's third consecutive #1 release in the last few years.
