From Unicorn Digital :-

Hamadryad is a group of musicians all driven by the same passion: musical creation. Their music tastefully blends progressive and classic rock, with a touch of cinematic vision, taking the listener on a musical adventure. (In classical mythology, the Hamadryad was a wood nymph fabled to live and die with a tree to which she was attached. Her mission was to be the link between the mortal and immortal entities.) Hamadryad’s musical mission is to take their audience on a journey that transcends passing trends.
