 This was her standard stage costume in the spring and summer of 1970.She chose the new costumes after her friend and designer, Linda Gravenites (whom Joplin had praised in "Vogue"s profile of her in its May 1968 edition), cut ties with Joplin shortly after their return from Brazil, due largely to Joplin's continued use of heroin.During the "Festival Express" tour, Joplin was accompanied by "Rolling Stone" writer David Dalton, who later wrote several articles and two books on Joplin.
