he was also running around signing to a bunch of different labels like how Kool Keith used to do.
if we want to be all the way 100% Kool Keith was the blueprint for that late 90's early 00 independent label hustle grind. get a bunch of small non exclusive advances. use aliases and drop a bunch of shyt
King Gidora
MF DOOM
Victor Vaughan
Dr. Doom
Kool Keith
Black Elvis
etc etc.
by the time he got that Adult Swim fame he was set in his ways. Doom took advantage of labels on some real villain shyt all the way till the end. He sold the same tracks to stonesthrow and adult swim. Didn't care for the fame push or money. took bags home and on some real shyt JJ Doom is ahead of its time. Not many could pull that record off.
Also, Doom took his art very seriously and refused to compromise his sound or rapping style for the masses.
He even said on that 2nd Vikor Vaughn album that he did the album for the advance yet it still stayed true to his core sound despite it being a let down.
He could've easily dropped more promised albums that would've gave him more buzz but he held off on them until he felt the time was right.
He also remained elusive and stayed under the radar.
Nothing about Doom was meant to be for the mainstream. He rarely did hooks, didn't feature big names in the music industry, didn't chase clout, didn't have much of a social media presence, didn't have the hottest beatmakers, didn't make club/radio songs, didn't sing much(except in an ironic way like Biz Markie), etc.
His style was underground in the true sense and he preferred to keep it that way. That JJ Doom album was the closest he came to putting out a contemporary sounding album and even that still had dense rhymes and a whole Afrocentric song about melanin.
Doom didn't want nor need the masses. That was literally the whole point of his persona and career choices.
