Haddad's quartet blends Flamenco, Jazz and Middle Eastern influences to create an evocative and magnetic new music. The Quintet released their first CD ‘Days Distinctive’ on 30th January 2012 on Weave Records to a great response from critics. Drawing on firm roots in Middle Eastern music and Flamenco, Haddad's compositions take listeners on a journey through Andalusia and the Middle East, conveying a sonic experience that can only be described as his own.
