Review by Stephen Thomas Erlewine (allmusic.com):
On the surface, the single-disc hits compilation The Immaculate Collection appears to be a definitive retrospective of Madonna’s heyday in the ’80s. After all, it features 17 of Madonna’s greatest hits, from Holiday and Like a Virgin to Like a Prayer and Vogue. However, looks can be deceiving. It’s true that The Immaculate Collection contains the bulk of Madonna’s hits, but there are several big hits that aren’t present, including Angel, Dress You Up, True Blue, Who’s That Girl and Causing a Commotion. The songs that are included are frequently altered. Everything on the collection is remastered in Q-sound, which gives an exaggerated sense of stereo separation that often distorts the original intent of the recordings. Furthermore, several songs are faster than their original versions and some are faded out earlier than either their single or album versions, while others are segued together. In other words, while all the hits are present, they’re simply not in their correct versions. Nevertheless, The Immaculate Collection remains a necessary purchase, because it captures everything Madonna is about and it proves that she was one of the finest singles artists of the ’80s. Until the original single versions are compiled on another album, The Immaculate Collection is the closest thing to a definitive retrospective.
On September 4 1987, Madonna performed “Causing A Commotion” live via satellite from the Stadio Communale in Turin, Italy, during the “Who’s That Girl World Tour” and won Best Female Video for “Papa Don’t Preach” at the 4th annual MTV Video Music Awards at the Universal Amphitheatre in Los Angeles, California.
On August 25 1987, “Causing a Commotion” was released as the second single from the soundtrack album “Who’s That Girl“, by Sire Records. “Causing a Commotion” was written and produced by Madonna and Stephen Bray, the song was inspired by Madonna’s relationship with then husband Sean Penn, and his abusive and violent nature.
On August 22 1987, Madonna’s “Who’s That Girl” single (from the soundtrack album of the same name) went to number-one on the US Billboard Hot 100.
Regarding the development of the music for the film, Madonna explained:
“I had some very specific ideas in mind, music that would stand on its own as well as support and enhance what was happening on screen and the only way to make that a reality was to have a hand in writing the tunes myself. The songs aren’t necessarily about Nikki [her character name in the movie] or written to be sung by someone like her, but there’s a spirit to this music that captures both what the film and the characters are about, I think.”
