Just in time for the Chairman''s centennial, the endlessly absorbing sequel to James Kaplan''s bestselling Frank: The VoiceFinally the definitive biography that Frank Sinatra, justly termed ''The Entertainer of the Century,'' deserves and requires. Like Peter Guralnick on Elvis, Kaplan goes behind the legend to give us the man in full, in his many guises and aspects: peerless singer, (sometimes) powerful actor, business mogul, tireless lover and associate of the powerful and infamous.In 2010''s Frank: The Voice, James Kaplan, in rich, distinctive, compulsively-readable prose, told the story of Frank Sinatra''s meteoric rise to fame, subsequent failures, and reinvention as a star of the stage and screen. The story of ''Ol'' Blue Eyes; continues with Sinatra: The Chairman, picking up the day after Frank claimed his Academy Award in 1954 and had reestablished himself as the top recording artist in music. Frank''s life post-Oscar was incredibly dense: in between recording albums and singles, he often shot four or five movies a year; did TV show and nightclub appearances; started his own label, Reprise; and juggled his considerable commercial ventures (movie production, the restaurant business, even prizefighter management) alongside his famous and sometimes notorious social activities and commitments.
