The album was named Last 2 Walk because DJ Paul and Juicy J were the last two members remaining in Three 6 Mafia. Crunchy Black left the group in late 2006 because of money disputes. "Doe Boy Fresh" featuring Chamillionaire, released on January 2, 2007, as a digital download, was intended to be the first single, but was ultimately cut from the album. The album's lead single, "Lolli Lolli (Pop That Body)", reached number 18 on the Billboard Hot 100.
Last 2 Walk was met with mixed or average reviews from music critics. At Metacritic, which assigns a normalised rating out of 100 to reviews from mainstream publications, the album received an average score of 56, based on thirteen reviews.[1]
Steve 'Flash' Juon of RapReviews recommended the album for "those who can get past their banal lyricism, because between the beats and the guest stars on this album they've got a winning combination anyway".[6]Jody Rosen of Rolling Stone found "every track is compelling, with synthesized strings and the usual depth-sounder bass lines inflated with reverb into miniature symphonies".[7] Tom Breihan of Pitchfork wrote: "somewhere on the way to novelty-fame, Three 6 Mafia lost something, and these days they sound like they're just going through the motions".[5]
In mixed reviews, AllMusic's David Jeffries stated: "there's no evidence Three 6 had a fully formed Most Known Unknown-styled album in them either, so consider the uneven Last 2 Walk a fair and necessary placeholder effort with a bit of "back to basics" thrown in to satisfy the faithful".[2]Robert Christgau of MSN Music wrote: "it's easy out there for an Oscar winner, but you'd never know it from these entertainment moguls, who pretend or report that they're still investing in mayhem, misogyny and sales careers whose main drawback is that they can get you arrested".[4] Andy Battaglia of The A.V. Club resumed: "but for all the intricacy on display in the production, the vocals just aren't there".[9] Daniel Brockman of The Boston Phoenix concluded "a club-banging record, but it's hard to recommend something so by-the-book". Ajitpaul Mangat of Tiny Mix Tapes wrote: "Three 6 Mafia's aspiration to evolve seems to have manifested itself on Last 2 Walk, from production to sound to lyrics. Having taken their novel sound to its lofty limits, it is time for the group to change and progress towards another musical frontier. However, their aspirations of progressing by melding Hollywood and the hood have largely failed".[11]
In negative reviews, Chase Hoffberger of The Austin Chronicle stated: "save for Lyfe Jennings' refreshing cues on 'Hood Star', there's nothing original about Last 2 Walk".[8]
