Congress Shall Make No Law... is an album by Frank Zappa, released posthumously in 2010 by the Zappa Family Trust on Zappa Records.
 It contains a full recording of Zappa's September 19, 1985, testimony before the United States Senate Committee on Commerce, Science and Transportation, during which he spoke in support of the recording industry and against censorship.
 In his testimony, Zappa criticized the Parents Music Resource Center, formed in 1985 with the stated goal of increasing parental control over the access of children to recordings deemed to have violent, drug-related or sexual themes by labeling them with Parental Advisory stickers.

 This album carried the Parental Advisory labeling--this was noted in the album's opening track, "Warning Parental Advisory".
The Parents Music Resource Center (PMRC) was an American committee formed in 1985 with the stated goal of increasing parental control over the access of children to music deemed to have violent, drug-related or sexual themes via labeling albums with Parental Advisory stickers.
 The committee was founded by four women: Tipper Gore, wife of Senator and later Vice President Al Gore; Susan Baker, wife of Treasury Secretary James Baker; Pam Howar, wife of Washington realtor Raymond Howar; and Sally Nevius, wife of former Washington City Council Chairman John Nevius.
 They were known as the "Washington Wives" – a reference to their husbands' connections with government in the Washington, D.C. area.
 The PMRC eventually grew to include 22 participants before shutting down in the mid-to-late 90's.

"Darling Nikki" is a song produced, arranged, composed and performed by American musician Prince and originally released on his Grammy Award-winning 1984 album, "Purple Rain".

 Compared with the slick production of the other songs on the album, "Darling Nikki" was deliberately engineered to have a raw, live feel.
