Damour vocal band is an acapella band that was established in the winter of 2011, by Faraz Khosravi Danesh and Ata Hakkak’s consultation. “Damour” is a Persian word which means a soft and tender voice, chosen in relation of the band’s function. The band’s repertoire is a selection of both instrumental and vocal music, from classical, pop, and folkloric genre. These pieces are arranged for four to six polyphoniclines, which are performed in a way that the audience would hear the sound of different musical instruments such as: Drams, Bass Guitar, Trumpet, Nay, Duduk and etc. With this kind of arrangement, Damour is able to perform instrumental music only with the human’s voice. Damour’s first public performance won the third place at the twenty seventh international Fadjr festival. They also have held up a lot of concerts from the year 2012-2015, and performed in solidary concerts with the well known singers of Iran. Some of Damour’s other activities are: live performances at IRIB’s (Islamic Republic of Iran Broadcasting) international programs , composing and performing different teasers and closing credits of IRIB’s TV programs . Quality of live performances, Musicality, Gaining audience’s attraction and connecting with them andrearranging the great pieces of Iranian music history with a new approach are the main goals of Damour Vocal Band. We hope to create a new platform in the field of Iranian vocal music which can someday lead the young musicians to continue what Damour has started.
