 During late August, September, and early October 1970, Joplin and her band rehearsed and recorded a new album in Los Angeles with producer Paul A. Rothchild, best known for his lengthy relationship with The Doors.Although Joplin died before all the tracks were fully completed, there was enough usable material to compile an LP.The posthumous "Pearl" (1971) became the biggest-selling album of her career and featured her biggest hit single, a cover of Kris Kristofferson and Fred Foster's "Me and Bobby McGee" (Kristofferson had previously been Joplin's lover in the spring of 1970).
