A well reviewed book that takes a closer look at the phenonmenon that Elvis Prestley still is - Kindle Edition is currently free to pick up.
Elvis Presley made over 700 recordings during his life. This book examines all of them.
Session by session, song by song, Reconsider Baby takes the reader on a journey from Elvis’s first recordings in 1953 through to his last performances in 1977. This significantly expanded and revised edition of 2014’s Elvis Presley: A Listener’s Guide provides a commentary on Elvis’s vast and varied body of work, while also examining in detail how Elvis and his recordings and performances were discussed in newspapers, magazines, and trade publications from the 1950s through to the 1970s.
The text draws on over 500 contemporary articles and reviews, telling for the first time the story of how Elvis and his career played out in the printed media, and often forcing us to question our understanding of how Elvis’s work was received at the time of release.
Hope it helps someone.
