AMB started out releasing albums for local labels. The 2005 Underground Psychos contest held at the Gathering of the Juggalos won them a one-album contract with Psychopathic Records. Violent J had high hopes for the duo, considering them to be "the future of Psychopathic Records" (along with another new artist signed by the label at the time, Boondox).
AMB left after their sole Psychopathic release, continuing to release albums on their own label, Canonize. They had two releases on the Psychopathic subsidiary Hatchet House in 2008 and 2010 and one more in 2014 followed by a Young Wicked solo album the following year, but AMB and ICP had a massive falling out over Young Wicked's relationship with the daughter of Jumpsteady (the girl is Violent J's niece). AMB ended up signing with Majik Ninja Entertainment, Twiztid's record label, which, along with the entire MNE label declining to appear at the Juggalo March, led to a falling out between ICP and Twiztid.
AMB provides the following tropes:
- Artifact Title: The meaning of the AMB acronym has gradually become this. Their earlier recordings, particularly their Psychopathic releases, showed overt Horrorcore shock value, but overtime, they've gradually toned down the horror themes in favor of more straightforward Hip Hop lyrical themes and trying to be less of a "Horror Rap" act and more just straightforward Hip Hop.
- Bread, Eggs, Milk, Squick: "Crazy" mentions breaking into an ex-girlfriend's house, eating Cap'n Crunch and then killing her dog.
- Call-Back: Blood In, Blood Out opens and closes with AMB singing a capella, with string instruments creeping in during the outro. Body In A Hole opens and closes with the same beat and scratching, with the outro revealing that the refrain of "The Garcia Brothers!" is the title of their next album.
- I Love the Dead: "Old Girl" tackles this with a Black Comedy approach (although AMB's promotional clip of this song simply implies that she's a bag lady and not a corpse). A significantly darker take on this is "God Only Knows".
- Shout-Out: Their name is a reference to a lyric from Insane Clown Posse's song "Bring It On", in which Shaggy 2 Dope calls himself an "axe murder boy".
- Shrouded in Myth: After they left Hatchet House in 2010, there were numerous rumors about their departure (including claims that Otis or Bonez had sex with the girlfriend of one of the label's higher-ups, which was revealed to be untrue). Psychopathic has dismissed all of them, and both parties indicated that the separation was on good terms.
- Surprisingly Gentle Song: "Blood In" and "Blood Out", the intro and outro, respectively, of Blood In, Blood Out, may qualify as this, if what they were singing about wasn't murder.
- Same goes for "God Only Knows", which is not as abrasive as some of their other songs, but still creepy as hell and talks about murdering a woman, keeping her body at the murderer's house, having sex with her corpse and eating her flesh.
- "Honor"
