This is the second biography of Sarah Vaughan (1924–1990), whose towering vocal talents took her to the top rung of the jazz ladder, beside Billie Holiday and Ella Fitzgerald. The author, trained as a classical musician, puts far more emphasis on the singer's recordings than Leslie Gourse did in Sassy, her 1993 Vaughan biography. Hayes's grasp of music, and her definitions of the musical terms she uses, make this the better account.

It was a real treat being able to talk with Paul Barton about the PSB M4U 8 and NAD HP70 at RMAF last year. Paul has lead acoustic design for PSB, NAD, and Bluesound for a long, long time now; he's got a strong understanding of audio and when he designs a product it speaks of this knowledge. In listening to this headphone, I find myself listening to both the headphone and what Paul may be trying to tell us with them. It's been an interesting dialog.
