Yana "Yanka" Stanislavovna Dyagileva (Russian: Яна Станиславовна Дягилева; 4 September 1966 – c. 9 May 1991) was a Russian poet and singer-songwriter and one of the most popular figures of her time in Russia's underground punk scene. She both played solo and performed with others, including Yegor Letov and bands Grazhdanskaya Oborona and Velikiye Oktyabri ("Great Octobers"). Dyagileva was greatly influenced by Letov and Alexander Bashlachev, who were her friends. Her songs explored themes of desperation and depression, punk-style nihilism, and folk-like lamentations.
Yanka (born Yana) Dyagileva was born on 4 September 1966, in Novosibirsk, USSR to Stanislav Dyagilev and Galina Dyagileva, both engineers. She was of Russian, Ukrainian and Czech origin. In 1973 she attended public school and studied piano for a year at a music school before quitting. This sparked her interest in the guitar. While still in school Yanka started writing poems (which have been lost) and performing, singing and playing guitar in school talent shows. In 1984 she entered the Novosibirsk Institute of Water Transport Engineers, but dropped out in her sophomore year. During this period she performed with the political band AMIGO. The earliest of Yanka's poetry that has survived is from 1985. In December 1985 she traveled to Leningrad, where she may have met Alexander Bashlachev. In October 1986 Yanka's mother died of cancer.
