Flag of Democracy: Flag of Democracy (often abbreviated F.O.D.) is an American hardcore punk band formed in 1982 and originally from Ambler, Pennsylvania, a suburb of Philadelphia.  The group plays a mixture of melodic punk, frequently with two-part vocal lines, and noisy, dissonant hardcore, often at extreme speeds – many F.O.D. songs push past 200 beats-per-minute.  The band never attained commercial success, but enjoys popularity in certain underground circuits, particularly in Europe.  They were referenced in lyric by fellow Philadelphia-area rock group the Dead Milkmen in the songs "Nutrition" and "Milkmen Stomp."

Lust Control: Lust Control is a Christian thrash punk band, originally formed in 1988.  They are known for their explicit lyrical content, which is devoted to matters of sexual purity and sin, including abstinence, masturbation, pornography, sex ed, and related topics.  For their unwavering views on sexual purity, "CCM" magazine has called Lust Control as "the Josh McDowell of the Christian rock world."  Musically they have been likened to The Ramones or The Dead Milkmen.  The band formed as a joke and was not meant for long term exposure, which has led some to refer to it as a Christian version of Spinal Tap.  Lust Control received the title of "The Worst Christian Band of the Decade" for the 1990s from "HM".

The King in Yellow (album): The King in Yellow is the ninth studio album by The Dead Milkmen.  It is their first studio album in 16 years.

In February 2011, the album was mixed at Miner Street Studios by Brian McTear.  A CD release followed shortly thereafter.

The Black Math Experiment: The Black Math Experiment is a band described as a unique blend of 1980s synthpop and new wave music with similarities to “The B-52's crossed with Berlin, The Dead Milkmen, and Talking Heads.”  Based in Houston, Texas in 2004, the band is known for their offbeat pop songs with irreverent or strange lyrics (for example, "Evil Wizard Jesus").  They are known for elaborate live shows that integrate multimedia such as televisions endlessly running odd videos, evangelical-like pamphlets and baptisms, Christmas presents, and a toilet paper cannon, all led by the inexhaustible energy of lead singer Jef With One F (Jef Rouner).  They received notoriety with their song, “You Cannot Kill David Arquette”.

Death Rides a Pale Cow (The Ultimate Collection): Death Rides a Pale Cow is a greatest hits release by Philadelphia based punk rock band The Dead Milkmen in 1997.  It contains the two previously unreleased songs "Milkmen Stomp," and "Labor Day," along with 21 others songs including the band's close brush with the mainstream "Punk Rock Girl."  The band was unable to include tracks from "Soul Rotation" and "Not Richard, But Dick" as Hollywood Records still retained the rights.
