Yea if you're looking for some great music for deep inflection, I would double down on Tool. Maybe Undertow or Ænama wouldn't be great starter albums, but Lateralus, 10000 Days, or Fear Inoculum have plenty of great, deep songs. Honestly though, fourty6-2 from Ænama is literally about inflection of one's self, and identifying your inner flaws/demons, great song.
