"In Winter" is truly unique collection of songs centered around the theme of winter, performed by multi-award-winning recording artist Katie Melua and featuring the astounding voices of Gori Women's Choir. Ranging from original works inspired by Melua's childhood in Georgia, to new interpretations of traditional carols, the album features arrangements of world-renowned choral arranger Bob Chilcott. In Winter opens up with the traditional Ukrainian Carol introduced to the West as Carol of the Bells, and closes with a show-stopping rendition of O Holy Night.

Compiled by Katie, the Ultimate Collection features 30 tracks from her 7 studio albums alongside her cover of "Fields of Gold" and two brand new recordings of Simon & Garfunkel's "Bridge Over Troubled Water" and Shirley Bassey's "Diamonds Are Forever". Singles on the album include her worldwide hit "Nine Million Bicycles", "The Closest Thing to Crazy", and "If You Were A Sailboat" as well as "What A Wonderful World" featuring Eva Cassidy.
