I don't think I've read a more thoroughly researched book on a group of people like Titanic's orchestra than "The Band That Played On: The Extraordinary Story of the 8 Bandmembers That Went Down with the Titanic " by Steve Turner. Mr. Turner had very good luck in researching for his book because all these little details that are only known by handful of people in the world such as town historians and the descendants of those who were with bandmembers. Reading the book allows you to get to know each of the members of her infamous orchestra fairly well and offers possible glimpses on what motivated them to stay back and play music while the lifeboats were loaded and lowered right in front of them. You are also transported back in time to the glory days of trans-Atlantic travel and the life of musician during the early 1900s as they travel on different ships and play with different orchestra. I give it 4 out of 5 stars simply because it can get boring at times. It's still well written and very informative if you wanted a book that would take you back in time to the life of a musician at that time.
