It's highly probable that any living music legend you could eavesdrop on during the recording of an album would unearth anecdotes and life lessons.
Celebrated American-standards crooner Tony Bennett is that guy in "The Zen of Bennett," filmed by his producer son Danny and director Unjoo Moon as he recorded last year's Grammy-winning "Duets II" on the cusp of turning 85.
Given an artfully lighted, lounge-club atmosphere (sometimes facile-ly so) by cinematographer Dion Beebe, the movie allows Bennett — mostly through overheard chats — to wax coolly on dressing well, how fame goes but quality stays, and the greats he's known: Basie, Ira Gershwin, Bill Evans. Of the youngsters he performs with, John Mayer makes him feel old, a flirty Lady Gaga makes him feel young and Michael Bublé speaks his language.
But it's his "Body and Soul" session with the late Amy Winehouse — the troubled singer's last recording, and a Grammy-winner for pop duo/group performance — that gets you: her jumpy, respectful nervousness, the way he calmly soothes and inspires her by invoking Dinah Washington, and the roiling soul of the takes that follow.
