The 27 Club refers to a group of musicians who all died at the age of 27. The club is also known as the Curse of 27 and Club 27 and it is often referred by other names as well. All of the musicians have several things in common, all of them were famous musicians and of course they were all 27 when they died.
The idea of the club first started after several famous and renowned musicians died all of them at the age of 27. Many consider the first "member" of the club to be Robert Johnson, legendary blues player. The thing that is interesting about Johnson compared to the other members of the club is that he already had a legend about his death, before the idea of the 27 Club came to be. Less known in his time but later would become legend that Robert Johnson became a master of the guitar in a very short time, because of this a legend formed that he sold his soul to the devil for mastery of his instrument.
The idea for the 27 Club first appeared in 1994, to that point there were already many famous musicians who all died at the age of 27. Robert Johnson, Brian Jones, Jimi Hendrix, Janis Joplin and Kurt Cobain after all of these musicians died a pattern emerged, they all died when they were 27 years old and that's how the 27 Club formed.
Almost all of the musicians that are usually included in the 27 Club had at least some controversy related to their death. Robert Johnson's cause of death is unknown to this day, though it is believed to have been strychnine poisoning. The circumstances of Brian Jones' death are also suspicious, he supposedly drowned in his swimming pool but it was speculated that he might have been murdered. Jimmy Hendrix suffocated after taking too many sleeping pills.
Throughout the years the 27 Club has remained controversial because of the suspicious deaths of its "members" and the "rock and roll" lifestyle they led.
