Tragic rock deaths: What Do You Think?

This week marks the 50th anniversary of The Day The Music Died -- that fateful day where Buddy Holly, Ritchie Valens, and the Big Bopper died in a plane crash while on tour. Although their deaths were certainly tragic, happening so swiftly and at such young ages, there are unfortunately plenty of other similar young deaths in rock... not just by air travel, but misadventure, suicide, even homicide. My question this week is: What was the first rock death that really affected you emotionally, and how did you handle it? Let me know what you think here.
