The song - per se - isn't new, and technically, it isn't hers.
"Avalanche" is a Leonard Cohen song from the early '70s, when I could still be considered a semi-wee lad.
The opening music is undeniably Cohen, and you feel him throughout the song.
Mann does a good job, but she usually does. If you're looking for 'up', this probably isn't gonna be it. But it is all nicely done.
