Margaret Price

Soprano -- via Gramophone.

Tony "Ham" Guerrero

Trumpeter and singer -- via the San Antonio Express.

Milton Babbitt

Composer -- via the New York Times. Although he may be dismissed by posterity as a serialist, his atonal work is rewarding for those who can stick it out. He was a bold and committed experimenter, equipped with a playful sense of humor. Blessed with profound mathematical gifts, he was among the first composers to write for electronic, synthesized and manipulated recorded music.

UPDATE: Robert Hilferty's documentary on Babbitt was stopped due to Hilferty's untimely death in 2009. Good news! Composer Laura Karpman was commissioned by Hilferty's companion Fabio Toblini to finish the film, and it's done. It can be seen here, and below --

Diana Norman aka Ariana Franklin

Journalist, freelance writer and novelist -- via the BBC.

John Barry aka John Barry Prendergast

Film composer -- via the BBC. A five-time Oscar winner -- not only one of the most popular film composers, but one of the most significant. He will be forever identified with his multiple James Bond movies scores, but his range was much broader, and his artistry was infinitely more subtle and affecting. 50 years -- 110 titles -- a mighty contribution. Also, a tribute and remembrance from the Guardian --
