Okay, so it may only be a “musical” in the eyes of the Hollywood Foreign Press, but even the “bad” music is great in Inside Llewyn Davis, the Coen Brothers’ tuneful, bittersweet study of a deeply talented failure amid the 1960s folk scene. As is their wont, the Coens lay on the dry satire as they turn the likes of Hedy West’s “Five Hundred Miles” into an impossibly earnest sham, set in stark contrast to the rich and raw poetry of the titular artist’s (Oscar Isaac) soul-bearers. But, as arranged by incomparable music producer T Bone Burnett, and as performed by co-stars Justin Timberlake, Carey Mulligan, and Stark Sands, the West cover still sounds gorgeous in all its tongue-in-cheek squareness, and it’s one of many songs that could humble Les Misérables in regard to the “novelty” of singing live on film. Isaac’s tracks, which are each flawlessly sung in scenes that operate as sober, angelic interludes to the film’s irony, are, unfortunately, all covers as well, leaving them ineligible for Original Song consideration (it would have been swell to hear Isaac croon traditional ballads like “Dink’s Song” or “The Death of Queen Jane” on the Oscar stage, but that won’t be the case). The only eligible track appears to be “Please Please Mr. Kennedy,” a political parody song penned by Burnett, Timberlake, the Coens, Ed Rush, and George Cromarty, and performed by Timberlake, Isaac, and a quasi-beatboxing Adam Driver. The song is deliberately un-soulful, but it’s an absolute hoot, and it has a good shot here if only because voters will want to squeeze in some music from the film.
