Not taking anything away from Havoc, that's my 3rd favorite producer ever...but his production never sounded like it did on The Infamous and I always attributed that to Tip.Tip mixed the whole album.
Those are his drums too. He gave Havoc his drum kits for a lot of those tracks. So joints like "Q.U. Hectic" and "Survival of the Fittest", all produced by Hav, but he was using Tip's kits. That's when the album turned around. Matt and Schott are my OG's, so I had the advance copy before Tip changed everything. Both versions are like night and day. He really made this album what it is today.
That's not a diss, if anything it makes Hav more impressive because I think HOE is him really digging into his own bag and the result is incredible.
