Some think of jazz as instrumental music, but it is also a ripe field for vocalists. Today’s jazz appreciation minute from jazz appreciation month features Ella Fitzgerald, one of the best. Her story is told in Ken Burn’s film Velocity of Celebration, which you can watch on our Kanopy trial. Sarah Vaughan, another consensus favorite, is featured in The Adventure and Billie Holiday in Pure Pleasure. All of them have albums that can be streamed on Hoopla.
