Inventions from the Blue Line

Inventions from the Blue Line is a 1994 music CD containing some of the best known TV cop-show themes written by Mike Post up to then.
The album includes several themes from the TV series "NYPD Blue". It also includes themes from the series "Law & Order", "Silk Stalkings" and "Renegade".
The cover of the album is taken in the style of the opening credits from the "Law & Order" TV series.
In the liner notes, Post discusses his late father, Sam Postil, and the admiration for law enforcement officers that Sam instilled in Mike. He also refers to police with the traditional nickname of "blues", as in "The Thin Blue Line" which refers to the police in general and to police camaraderie (one of the tracks is called "The Blue Line", which Post calls 'the comradery theme').
