Answer
Anti-formalism was a Soviet campaign associated with composer Tikhon Khrennikov. Launched in 1948, the campaign aimed to promote traditional Soviet values in music and art, criticizing works deemed overly abstract or experimental. Khrennikov, as a prominent composer and official in the Union of Soviet Composers, played a key role in enforcing the campaign's directives, which resulted in the suppression of many innovative and avant-garde artistic works.
