The Immaculate Collection is the first greatest hits album by American singer Madonna, released on November 12, 1990, by Sire Records. It contains fifteen of her hit singles recorded throughout the 1980s, as well as two new tracks, "Justify My Love" and "Rescue Me". All the previously released material was reworked using QSound audio technology, making it the first album to use the process. For the new material, Madonna worked with Lenny Kravitz and Shep Pettibone. The album's title is a pun on the Immaculate Conception, a Marian dogma of the Catholic Church.
