Pianist Tigran Hamasyan's Nonesuch Records debut, Mockroot, is out now, featuring new tracks written by Hamasyan, as well as his arrangements of traditional Armenian songs. Although trained as a classical and jazz musician, Hamasyan draws on a wide range of influences, including Armenian folk music, rock, electronica, poetry, and more. "There are many brilliant and perfectly finished young jazz pianists around," says the Telegraph, "but Hamasyan stands out because he has something important and urgent to say." "You will find it difficult if not impossible to get this disc out of your machine for quite a while," raves the Buffalo News. "Don’t count on getting it out of your head for a long while either." Hamasyan and his trio are currently on tour in the US.
