Where to start with Gesaffelstein’s music ?

Hey, I'm new here. I listened to Lady Gaga's new album (I'm a huge Gaga fan) and I liked Gesaffelstein's contributions to it. I already enjoyed the work he's done with The Weeknd, Charli XCX and Kanye West, but I'm not totally familiar with his music. I know some of his solo songs, but I’m not sure where to start with his discography and early unreleased works. What is Gesaffelstein's lore ? I noticed that he makes a lot of references to esotericism and his persona is some sort of perfectionist. His mask gives off a Machiavellian aesthetic in some way.
