....Azam Ali Greg Ellis Vas Izgrejala
In a career which spans over a decade and includes eight collaborative albums and solo albums, Azam Ali has confirmed her place as one of the most prolific, versatile, and gifted singers on the world music stage today. Her dedication to defying cultural specificity in music, and her unwillingness to settle into one form of musical expression have earned her the respect of both her peers and critics worldwide. When one looks at her entire body of work, it is hard to deny Azam her rightful place among the best singers and composers in music today.

Elysium for the Brave, Azam's second solo album, signals a new turn in her musical evolution. The album, her most ambitious work to date, brings together musicians from varied musical backgrounds performing in diverse permutations. Singing predominantly in English for the first time, the songs are based on lyrics written by Azam herself and reveal a poetic lyricism heard only in glimpses of her previous works.
