Tracks composed by the american multi-instrumentalist Aret Madilian, sang by the french singer Beatrice Valantin, the ancient wind instrument the duduk, played by the Armenian Gerard Madilian (unknown or no clear relation between Aret, the founder of the band and Gerard who share the same unusual last name) and a new comer Guillaume Leprevost, a bassist/guitarist, making his debut on this eighth Deleyaman album, Sentinel. Sentinel is a voyage into the depths of Deleyaman's musical universe and style. Its soundscapes, emotions and spirit evoke an enigmatic atmosphere and create an inner space between dream and reality. A new addition to Deleyaman's discography which consists of eight albums released over a span of nineteen years.
