In December 1973, a Paris publishing house began printing Aleksandr Solzhenitsyn's The Gulag Archipelago for the first time. The book, which exposed the full horrors of Soviet communism, has been cited as one of the reasons for the U.S.S.R.'s eventual collapse. Solzhenitsyn's son Ignat, an acclaimed New York conductor, spoke with RFE/RL about the relevance of the book today, and the dramatic events that preceded its publication.
