True Magic is a half arsed album used to fulfill a contract and isn't the best place to start. It was very poorly received. He's only got a small discography, with a few classics and a few curiosities that you might explore later.
Start with the Ecstatic, his last proper solo album. Great, varied late 00s Stones Throw production incorporating jazz, soul, reggae, afrobeat and other "world music". Then go to Black on Both Sides which is a 90s alt-hip hop classic, soulful, lyrical, following on from the Native Tongues sound of groups like ATCQ and blurring the lines with 90s neo soul. For me it's his defining statement but it's super long and kind of bloated so go for the leaner Ecstatic first.
Then there's the 1998 group album Mos Def & Talib Kweli Are Black Star with Talib Kweli. Two NY rappers at the top of their game over classic boom bap beats
Then you're pretty much done for LPs. Lots of good tracks and guest appearances otherwise though.
