The music industry's premier event will take place live on Sunday, February, 8, 2015, at STAPLES Center in Los Angeles and will be broadcast on the CBS Television Network from 8 to 11:30 p.m. (ET/PT).

Bennett & Gaga are nominated for a GRAMMY this year in the "Best Traditional Pop Vocal" category for their album CHEEK TO CHEEK.

CHEEK TO CHEEK features classic jazz standards sung by the pair in a combination of vocal duets and solo performances. Each song was handpicked by the artists, and the album features classic selections from the Great American Songbook including "Anything Goes," "It Don't Mean A Thing (If ItAin't Got That Swing)," "Sophisticated Lady," "Lush Life," and therecord's title track, "Cheek To Cheek."

Recorded in New York City, the record took over a year to complete and features jazz musicians associated with both artists including members of Bennett's quartet, Mike Renzi, Gray Sargent, Harold Jones and Marshall Wood as well pianist Tom Lanier. Jazz trumpeter Brian Newman, along-time friend and colleague of Lady Gaga appears on the album as well with his NYC based jazz quintet. Jazz soloists on selected tracks include tenor saxophonist Joe Lovano and the late flutist Paul Horn.
