This deceptively slim biography has taken me over a month to read because I wanted to make the most of the middle section, which is a comprehensive, track-by-track discography, with some passionate, sympathetic commentary. So, rather than spending around £150 on the whole collection, I used my free Spotify account to full advantage. I don't even like jazz as a rule! Still ended up spending over £50 on downloads - loved the early Columbia stuff, and fascinated by the carrier's twilight years. A true talent, a whirlwind of contradictions. I will definitely read more about her.
