Janis Lyn Joplin was an American singer considered the premier female blues vocalist of the Sixties; her raw, powerful and uninhibited singing style, combined with her turbulent and emotional lifestyle, made her one of the biggest female stars in her lifetime. She died of a drug overdose in 1970, aged 27, after releasing three albums. A fourth album, Pearl, was released a little more than three months after her death, reaching number 1 on the charts.
