From a musician standpoint, you also gotta include his work on the first two Fat Boys albums as well.
Kurtis Blow produced the records (probably Buff too...I'm sure he came up with MAD ideas on those accapella joints),
but Orange Krush (Larry Smith and Davy DMX) were gettin' busy with the instruments on joints like "Jailhouse Rap" and "Can You Feel It?".
