its not them its him, unless ur refering to his albums, Killer is a great album but i like K.O.D just as much if not more. Sickology 101 isnt really a "Tech N9ne" album its more of a colaboration of Strange Music's artist with a few other apperances but thats MO. His old school stuff like Anghellic,Absolute Power,Vintage Tech,EverReady are also great albums. To be truthful i like all his albums just the same, becasue he has sick flows and his songs are just crazy good, and they beat hard.
Vintage Tech was more of stuff from older work thrown on a CD. there is a few other albums that he has, but those are from an older record label he used to be a part of. the diffrence in those cd's to the cd's everyone now knows is like night and day.
