Here's another mind-numbing Busby Berkeley masterpiece, more reminiscent of Fritz Lang and G.W. Pabst netherworlds than the jaunty world of musicals. Berkeley's magnum opus, The Lullaby Of Broadway, requires two YouTube segments and starts with the longest transition from long shot to close-up in the history of movies.
The striking lead vocalist is Wini Shaw. She's in several mid-1930's Warners musicals, the 1934 Technicolor comedy short, What, No Men! - and later turns up in Soundies.
I'm dumbfounded by the sheer filmmaking brilliance of it all.
