Madlib is a genius, his body of work is incredibly consistent, especially considering the amount of stuff he's put out, aside from RZA, 'Lib is my favorite producer
Beat Konducta Vol 1-2 is good, but you need to listen to vol 5 - one of my favorite instrumental albums
If you're looking for more Madlib, check out:
Madvillainy ( masterpiece )
Quasimoto The Unssen ( 10 years old, still WAY ahead of its time, amazing production - if you don't like the way Madlib alters his voice on here I'd advise you to track down the instrumental version )
Beat Konducta Vol 5 ( tribute album to J Dilla, mixes both of their sounds perfectly - Anthenagin' (?) is one of my favorite beats ever )
Dudley Perkins - Experssions ( Madlib produced it all, some of his most soulful work is on here, only downside is that I'm not a fan of Dudley, but these beats are too good )
Lootpack - Soundpieces Da Antidote ( 90's Madlib, some great stuff on here )
Jaylib - Champion Sound ( J Dilla rhyming over Madlib beats, Madlib rhyming over Dilla beats

)
