The album's production was handled by Sarz, Cobhams Asuquo, Tee-Y Mix, and eLDee.

eLDee first announced the release date for Undeniable as 31 March 2012, although it was later pushed back to July.

Produced by Sarz, "Category" interpolates Nigerian musician Fela Kuti's "Teacher Don't Teach Me Nonsense" on the hook.

[6] Ayomide Tayo of Nigerian Entertainment Today described Undeniable as a carefully structured and well-produced album that showcases the rapper's legacy and versatility.

Praising tracks like "Higher" and "We Made It" for their nostalgic and lyrical depth, Tayo noted, "A true legend knows when to quit the game, and eLDee is leaving the stage when his contribution, influence, and legacy are undeniable."
