Billie Holiday, 1915-1959, was an American jazz singer and songwriter. Nicknamed “Lady Day” by her friend and musical partner Lester Young, Holiday had a seminal influence on jazz and pop singing. Her vocal style, strongly inspired by jazz instrumentalists, pioneered a new way of manipulating phrasing and tempo. From the book “We are all equal”, by Finn Nygaard.
