Don Cannon made a recent appearance on Math Hoffa’s My Expert Opinion and a debate broke out among the best producers of all time and Just Blaze’s name came up.

While many contenders were brought up from Just Blaze’s decorated production discography, the Generation Now co-founder kept coming back to Freeway’s “What We Do” as JB’s best work behind the boards.

“He got a couple but I’ma say ‘What We Do Is Wrong’ is his best beat ever,” Cannon said, which many agreed as a worthy contender.

Another person mentioned Cam’ron’s “Welcome to New York City” featuring JAY-Z and Juelz Santana.

“That might be No. 1,” Math Hoffa declared before adding The Dynasty: Roc La Familia‘s “Intro” track.

Don Cannon threw a few other Just Blaze productions into the mix including JAY-Z’s “Show Me What You Got,” “U Don’t Know,” “Public Service Announcement (Interlude)” and Dipset’s “I Really Mean It.”

Last month, Just Blaze surprised rap fans by unearthing a treasure trove of unreleased music, including never-before-heard material from JAY-Z, Ghostface Killah, Madlib and more.

The former Roc-A-Fella hitmaker shared a series of photos on Instagram showing several CDs he had dug up from his vast storage vault.

The collection included unreleased tracks from The Neptunes titled “Christies” and “Operator,” a Timbaland and Static Major Pro Tools session from 2002 featuring “three versions of hooks,” 9th Wonder beats and a Just Blaze and Ghostface Killah disc from 2006 labeled “Missing Audio Files.”

JAY-Z historians were in for a treat as Just’s haul also boasted a Hov and M.O.P. CD from 2002 dubbed “Laze Copy” and a JAY-Z and Just Blaze collaboration called “Hello Young Lady,” which was recorded at New York City’s Baseline Studios — Roc-A-Fella’s former home base — in April 2001.

Perhaps the most tantalizing of the batch, however, was a CD from 2007 featuring the names of JAY-Z, Madlib, Sleepy Brown, Beanie Sigel, Memphis Bleek and Trey Songz, which Just Blaze referred to as a “doozy.”
