The 27 Club is an informal list consisting mostly of popular musicians who died at age 27. As a pop-cultural phenomenon, it is closely linked to the urban myth that musicians' deaths are unusually common at 27. Although this claim has been refuted by scientific research, it remains a common cultural conception that the phenomenon exists, with many celebrities who die at 27 noted for their high-risk lifestyles. The original basis for the notion was a cluster of prominent musicians' deaths at the age of 27 between 1969 and 1971, including Brian Jones, Jimi Hendrix, Janis Joplin, and Jim Morrison; but only after the death of Kurt Cobain in 1994 was the notion of a "club" established, and the death of Amy Winehouse in 2011 enhanced its prominence. Different write-ups include a number of other musicians and sometimes other celebrities.
