"In most ways, American hardcore was all about breaking down walls and slaying sacred cows. That being said, most of the bands were surprisingly puritanical when it came to the subject of sex. With Slip It In, Black Flag got more risque than most hair metal bands dared in 1984. The distinctive Raymond Pettibon artwork pushed the boundary even further. The nun on the cover made it sacrilegious as well as salacious. They were also making songs longer than the typical three minute radio friendly ditties playing on the FM dial. It was certainly a far cry from their two minute blasts of rage that helped define the punk and hardcore genres. Slip It In has remained among the more underappreciated Black Flag albums." - Tom Trauma
