"Obscurity Knocks" is a song by Scottish band The Trash Can Sinatras, which was released in 1990 as an extended play[1] (and promotional single in the United States) from their debut studio album Cake.

"[5] Tim Southwell of Record Mirror stated, "'Obscurity Knocks' is an absolute howitzer of a single with one eye firmly on the Top 40, jangly guitars, a snappy beat and some marvellously intriguing lyrics providing the ideal backdrop for Frank's love-torn vocals.

[7] Andrew Collins of New Musical Express picked it as one of the magazine's "singles of the week" and described the EP as a "four-song miracle of human life" and "overwhelming winsome and winning".

[11] In a retrospective review of Cake, Norm Elrod of AllMusic described the song, along with the album's other singles, as the "tastiest pieces of pure pop pleasure".

[2] In a 1999 review of the album by CMJ New Music Report, Carlene Bauer commented: "'Obscurity Knocks,' a high-spirited grouse about fickle fame and fleeting youth, is the best - and eeriest - number.
