The EP contained the Dr. Dre diss track "Real Muthaphuckkin G's". Eazy-E released music videos for "Any Last Werdz" and "Real Muthaphuckkin G's". It went multi-platinum and became one of Eazy-E's most popular recordings. Eazy-E was originally intending to release a follow up to Eazy-Duz-It named Temporary Insanity, which was going to be released as a double album. However, after the several insults Dr. Dre made in The Chronic, Eazy-E decided to release this EP. Dr. Dre is mentioned on every track, but three: "Gimmie That Nutt", "Boyz N Tha Hood (G-Mix)" and "Any Last Werdz." The album is the first release under the newly established distribution deal with Relativity that allowed Ruthless Records ownership of its master recordings.
