The is borderline
for P, but his rapping on Albert Einstein in 2013 was the best piece of rapping he's done since MM and HNIC. It was clearly a level above any Infamy or beyond Mobb albums, and other solid solo projects he's done like Return of the Mac, HNIC 2, or Product of the 80's.
So IMO after Hell on Earth, the 3 albums that really are going to give you a good prodigy rapping are Murda Muzik, HNIC, and Albert Einstein.
Murda Muzik and HNIC were recorded around the same time so it's not a surprise that he raps with the same style on those. For example Quiet Storm was meant for HNIC but Prodigy let go of it for the sake of the group. And I forget if it's Delt with the Bullshyt or Wanna Be Thugs, but one of those 2 songs from HNIC was meant for Murda Muzik.
