Pancake Mountain is a children's television show based in Washington, D.C. Created by filmmaker Scott Stuckey (of the famous Stuckey's family), it is notable for featuring many punk rock/indie rock musicians like The White Stripes, Eddie Vedder, Fat Mike, The Melvins, Kings of Leon, Henry Rollins, Shirley Manson, Daniel Johnston, Tegan and Sara, Katy Perry, Bright Eyes, Deerhoof, Ted Leo and the Pharmacists, The Fiery Furnaces, Thievery Corporation, Arcade Fire, Built to Spill, Jenny Lewis, Metric and many others.

The Execution of All Things is the second full-length album released by Los Angeles-based indie pop band Rilo Kiley.  Expanding on their previous musical sound that mostly incorporated guitars, vocals, percussion and pianos, the album contains heavy electronica sampling mixed into the songs in a rather unusual and displaced-sounding way.  Also, unlike their previous tracks which were written in very traditional manners, the lyrics to the songs on "Execution" are very wordy and read like prose.  Musically, the record has a very sunny disposition, with bouncing bass lines and simple melodies complemented by lead singer Jenny Lewis's vocal style, but the upbeat music is generally counterpointed by the often dark and morose subject matter that the lyrics reference.  The album was recorded at Saddle Creek Records in Omaha, Nebraska, and the aforementioned features show the influence of that studio's associated Omaha Sound.
