Like others have said peep the Ken Burns Jazz documentary if you can. Its on Amazon Prime if any of you have it. Its long as shyt tho and I believe the best episodes are episode 7-10 which is more about the bebop era which is hands down the best jazz ever imo. I have a nice record collection with a ton of old school jazz records. Blue Note Records is/was the premier jazz label hands down. Love fusion as well but I'm always going to promote the best in bebop jazz.. Coltrane, Miles, Eric Dolphy, Herbie Hancock, Art Blakley, McCoy Tyner, Monk, Freddie Hubbard, Wayne Shorter, etc.
Also check out a Coltrane doc on Netflix, The 'Straight No Chaser' doc about Thelonious Monk, and peep the Blue Note IG account and peep some of their much heralded old school artwork and album covers:
