This new collection of the late American singer includes eight previously unheard songs.
Recorded at the Blues Alley jazz club in Georgetown, D.C, these 31 live tracks have been remastered - and they sound like a masterclass in live performance.
Whilst many would associate Cassidy with slow, tear-soaked numbers like Songbird and Somewhere Over the Rainbow, this album has a large number of up-tempo tracks.
The raw growl of her vocals in Next Time You See Me contrasts alluringly with the heart-breaking delicate version of Bridge Over Troubled Water.
And if you thought Songbird by Eva Cassidy was a classic, you haven't heard nothing until you've heard Nightbird.
You're bound to have heard a few of these songs before, probably on Radio 2, but this is more than a collection for a fan.
It's an immersive live experience that is sure to bring even more people to Cassidy's superb - but so sadly - small body of work.
