Janis Lyn Joplin (; January 19, 1943 - October 4, 1970) was an American rock singer and songwriter; one of the most successful and widely-known female rock stars of her era. After releasing three albums, she died of a heroin overdose at the age of 27. A fourth album, Pearl, was released in January 1971, just over three months after her death.
Kozmic Blues Band
After splitting from Big Brother and the Holding Company, Joplin formed a new backup group, the Kozmic Blues Band, composed of session musicians like keyboardist Stephen Ryder and saxophonist Cornelius "Snooky" Flowers, as well as former Big Brother and the Holding Company guitarist Sam Andrew and future Full Tilt Boogie Band bassist Brad Campbell. The band was influenced by the Stax-Volt rhythm and blues (R&B) and soul bands of the 1960s, as exemplified by Otis Redding and the Bar-Kays. The Stax-Volt R&B sound was typified by the use of horns and had a funky, pop-oriented sound in contrast to many of the psychedelic/hard rock bands of the period.  By early 1969, Joplin was allegedly shooting at least $200 worth of heroin per day (equivalent to $1300 in 2016 dollars) although efforts were made to keep her clean during the recording of I Got Dem Ol' Kozmic Blues Again Mama!. Gabriel Mekler, who produced Kozmic Blues, told publicist-turned-biographer Myra Friedman after Joplin's death that the singer had lived in his house during the June 1969 recording sessions at his insistence so he could keep her away from drugs and her drug-using friends.  Joplin's appearances with the Kozmic Blues Band in Europe were released in cinemas, in multiple documentaries. Janis, which was reviewed by the Washington Post on March 21, 1975, shows Joplin arriving in Frankfurt by plane and waiting inside a bus next to the Frankfurt venue, while an American fan who is visiting Germany expresses enthusiasm to the camera (no security was used in Frankfurt, so by the end of the concert, the stage was so packed with people the band members could not see each other). Janis also includes interviews with Joplin in Stockholm and from her visit to London, for her gig at Royal Albert Hall.  On one episode of The Dick Cavett Show, they performed "Try (Just a Little Bit Harder)" as well as "To Love Somebody". As Dick Cavett interviewed Joplin, she admitted that she had a terrible time touring in Europe, claiming that audiences there are very uptight and don't "get down".
