Madlib is less a musician than a universe— he started out making beats, but now he makes worlds and atmospheres, and he started out crate-digging but now he magically and cosmically creates, with records and/or instruments and/or samplers and his own unflaggingly iconoclastic inspiration. You can explore his discography (20+ years of it) like you’d explore anything else— find a place where the terrain looks inviting, and wander on in. (Maybe the Medicine Show series? Or the classic Madvillainy?) Jazz? Hip-hop? Music from several decades and several continents? He’s worked with it all, and when he DJs, he’ll make it work on you.
