[12] On May 19, 2013, Cee Lo Green announced at the Billboard Music Awards that the album's official release date would be changed to August 27, 2013.
[20] According to Cee Lo, a collaboration with Eminem was set to take place, but the latter artist eventually backed out of the project, apparently because of the other commitments he had made in his personal life.
[20] "Pinstripes", which is a collaboration with Atlanta-raised hip hop artist T.I., makes reference to the group's 1995 single, "Cell Therapy".
"[29] Andy Gill of The Independent said, "In the 14 years since World Party, Cee Lo Green has entirely overshadowed his former Goodie Mob friends, and that dynamic dominates this comeback reunion album.
"[25] Jason Lymangrover of AllMusic said, "By the end of the album, Cee Lo's presence dominates and songs start falling closer to material from The Odd Couple.
"[22] Alex Macpherson of The Guardian stated, "The 18-track culmination of a reunion that's been brewing longer than the full line-up of Goodie Mob lasted first time around, Age Against the Machine feels less like a grand comeback statement to lay the group's demons to rest and more like sweeping up forgotten odds and ends from the studio.
Club said, "Age Against The Machine takes Green's skill with the musical mainstream and gleefully showcases it in a track about interracial relationships and hiding from bigoted white fathers is evidence enough that Goodie Mob is back.
"[23] Emanuel Wallace of PopMatters stated, "At times, the forward sound of Age Against the Machine has the feel of a Gnarls Barkley album, but the content is anything but that.
"[27] Ryan Reed of Paste said, "Age Against the Machine isn't a seamless reunion—it's too messy, too bloated (18 tracks, not a single necessary interlude), too Green-centric to feel like a pure collaboration.
"[28] Elysa Gardner of USA Today said, "Fourteen years after their last album, Cee Lo Green and his friends reunite, with their humor, ferocity and grooviness intact.
"[30] Reed Jackson of XXL stated, "Age Against The Machine can still be considered a success for its willingness to be different, which has been the mob's mantra for its entire career.
Rather than being safe and returning to its roots, the mob decided to look to the future and craft an album they believed would bring something new and refreshing to the table.
"[31] Omar Burgess of HipHopDX said, "It's nearly impossible to expect a group to be capable or interested in an exact replica of material they made almost 20 years ago.
"[32] Jim Farber of the New York Daily News stated, "On "Age Against the Machine," the Mob specialize in neurotically speedy beats, head-spinning arrangements, and rapping that veers between the absurdist and the politically pointed.
