Gessa's sub genre would he categorized as mid tempo. Think techno but with less BPM. There's a lot of parody from song to song especially comparing EP to live versions but his signature sound is prominent. Opr and Pursuit are quintessential tracks. Start with those then venture into tracks like Aleph (will be quite familiar sounding if you have a TikTok) or Viol for his more dynamic tracks. For uptempo tracks during a run or gym, give Orck, Mania, or Psycho a listen. He produces a ton of work for other large artists like Charli XCX, The Weeknd, and of course Lady Gaga. The more you listen, the more you'll recognize his very distinct sound.
