Some words for this work:
A special, newly commissioned work based on the poetry of Leonard Cohen.
Conceived by Philip Glass over 6 years ago after Cohen himself wrote him most of the writings now published as "Book of Longing", this music is the culmination of the mutual admiration between two celebrated and uncompromising artists.
Glass sets Cohen’s deeply personal and provocative words to a new score, performing with a new ensemble of singers and musicians.
