my thoughts on Kool Keith are highly unusual. the guy has a TON of material. most of it, I do not like.
however, Critical Beatdown is a CLASSIC album, I still play it today, but I play the deluxe version that includes those singles and original versions that were not on the original release. Kool Keith's vocals on that album are not only astonishing but words cant describe how influential it was in changing the rap styles, particluarly with his on-beat off-beat multi cadence flow. I am a HUGE Ultramag/Kool Keith fan based off that ONE album alone! Also love Funk Your Head Up and Four Horsemen. I am not as big of a Kool Keith fan as a solo artist, but has has had a solid discography.
I loved Dr. Octagon, it was a surprising release to me when it dropped. Cenobites was good. Most of his Kutmaster Kurt stuff was good, like Diesel Truckers, Masters of Illusion, etc...but Sex Style is my favorite solo album. Big Time (Ultra) was good. He dropped like 3 albums last year. Also he works with Ray West. Most notably LuvNY.
He has a ton of music, a lot of it I dont fukk with but there was a radio dj that recently ranked the top 5 MC's from each borough. this guy doesnt give a damn about popular opinion so I have no problem with his lists. He ranked KGR as #1 out of Queens. Sean Price as #1 out of BK. Long Island - Rakim of course.
His BX top 5 was, Kris, Ricky D, Pun, Lord Finesse, and Kool Keith
