They are the tenth and eleventh tracks and third single from the group's fourth studio album, "Insomniac".  The two songs were released as one single, as the songs are transitional - "Brain Stew" segues directly into "Jaded".  After 9/11, "Brain Stew" was placed on Clear Channel's list of post-9/11 inappropriate titles.  The song "Brain Stew" is about insomnia which comes from Armstrong's own insomnia.  The title track "Brain Stew" is named after Armstrong's friend, James Washburn aka Brain Stew.

The band have been said to make "fuzzy stripped-back rock’n'roll noise with a generous helping of weird."  The band's name is taken from the Roky Erickson & The Aliens song (Which in turn was taken from the 1955 film of the same name), with Struyf citing Erickson's former band The 13th Floor Elevators and the man himself as influencing Creature with the Atom Brain's sound.

The Trilogy Vinyl: The Trilogy Vinyl is a compilation of three albums by American sludge metal band Melvins, "The Maggot", "The Bootlicker", and "The Crybaby", which were released one after another in a series, within a timespan of one year, with similar album covers.  It was released exactly the same day that The Crybaby was released.  The compilation lists that every song from all three albums is present, though it is not.

Colossus of Destiny: Colossus of Destiny is a live album by the Melvins, which was released in 2001 through Ipecac Recordings.  It was recorded live Friday, December 13, 1998 at Club Mangler, Cupertino, California.  It is nearly an hour of synthesizer and sample experimentation ending in a performance of the song ""Eye Flys"".  It was reported that members of the audience were lying on the ground, covering their ears during this performance.  The album was originally intended to be the third part of the band's 1999 album trilogy ("The Maggot", "The Bootlicker" and "The Crybaby") until they came up with the guest star idea for "The Crybaby".

Mrs. Washington: "Mrs. Washington" is a song written and performed by Gigolo Aunts and the title song from their 1993 and 1994 singles.  The song also appears on the album, "Flippin' Out".  The August 1993 7" single (catalog number: SM1 or 7SM1) includes a cover of "Serious Drugs", a 1992 single by BMX Bandits later included on their 1993 album, "Life Goes On".  That 1993 single was the first in a series of five releases by various bands on Fire Records under the Spawning Monsters moniker.  The April 1994 7" single (catalog number: blaze68) and CD single (catalog number: blaze68cd) include a cover of "Ask", a 1986 single by the Smiths that later appeared on their 1987 albums, "Louder Than Bombs" (US) and "The World Won't Listen" (UK).  The 12" single includes a cover of "Can You Get to That" by Funkadelic, a song from their 1971 album, "Maggot Brain".  Both the 12" single and the CD single include a cover of "Winsor Dam", a 1991 recording by Big Dipper that did not receive its formal release until the 2008 compilation album, "".  Note that while both the 12" single and CD single attribute the writing credits for "Winsor Dam" to Goffrier/Oliphant/Michener/Wallik, other sources identify the writer of the song as Big Dipper guitarist, Gary Waleik.  The 1994 single entered the UK singles charts on April 23, 1994, spending only one week there.  The cover art of the 1994 7" single, 12" single, and CD single features Chloë Sevigny.  The photo appears to be from the same session as the photo on the cover of the Full-On Bloom EP.
