Query: An Insight To Understanding His Poems

"The Noise Of Time" is an excellent book to understand the background on the development of this great Russian poet. This autobiography engages all your senses with vivid and detailed description of his youth in St. Petersburg before the World War 1. Be warn readers, avoid reading the long Introduction by Clarence Brown; it is the best sleeping aid in the world.
