Amy Winehouse’s debut album helped make her a star in the U.K. but it wasn’t until she released “Rehab” from her second album that she became famous in the U.S. It was easy to tell that the pain in Winehouse’s voice was real but that helped her relate to her fans even more. The “Back to Black” singer publicly battled her demons with drugs and alcohol and towards the end of her career, she struggled to get through a performance. In 2011, Winehouse was found dead and alcohol poisoning was later ruled the cause of death. Winehouse died at the age of 27 in the same manner as other popular musicians who are a part of the 27 Club.
