By the time of this recording, Warren Rogers and Joe Kelley had traded instruments and David Wolinski had been added on keyboards.

"Bad Little Woman", a cover of the Belfast band The Wheels, backed by "Gospel Zone" was released as the first single, but only charted as high as # 91.

A third single at that time, "Willie Jean" (a Hoyt Axton tune incorrectly identified on the label as "traditional")/"The Behemoth" did not chart.

In a retrospective review for AllMusic, Bruce Eder noted "the original LP version of this album, the second by the legendary white Chicago garage punk/blues outfit, was one of the most sought-after artifacts of mid-'60s punk rock.

Back Door Men was a loud, feedback-laden, sneering piece of rock & roll defiance, mixing raunchy anthems to teenage lust (Gospel Zone', 'Bad Little Woman'), covers of Chicago blues classics (Willie Dixon's 'Spoonful', Jimmy Reed's 'Peepin' and Hidin'), raga rock ('The Behemoth'), folk-rock ('Hey Joe', 'Three for Love', 'I'll Make You Sorry'), and a blues-punk grab off of commercial Top 40 ('Tomorrow's Gonna Be Another Day'), all on one 12" platter.
