Aleksei Ivashchenko (Russian: Алексей Игоревич Иващенко, born 12 May 1958 in Moscow) and Georgy Vasilyev (Russian: Георгий Леонардович Васильев, born 22 June 1957 in Zaporizhia, Ukraine) are a Soviet/Russian bard duo, informally known as Ivasi (a pun on the "iwashi herring"). They wrote and staged the musical Nord-Ost.
