In Focus Features’ press notes, Ethan Coen clearly stated that A Serious Man “takes place in 1967.” (And particularly during the “summer of love.”) And yet when the Columbia Record Club guy calls Larry Gopnik (Michael Stuhlbarg) about late payments, he mentions two 1970 albums — “Santana Abraxas” and Creedence Clearwater Revival’s “Cosmo’s Factory.” The Coens are very exacting screenwriters and filmmakers so why would they do this? They could have easily fixed this.

Speaking of that period, The Yardbirds‘ “Shapes of Things” (released in February ’66) was a very audacious and avant garde single for its time. A progressive leap forward and a commercial hit in one brilliant cut.
