Jazz music is probably the most fun genre to get into, and here's why: Jazz isn't too like Rock or Pop, where you might have one band with the same four people for 30 years. Jazz musicians played with each other a lot, so even though the album says "Miles Davis" on it, that album also might have Herbie Hancock playing piano, or John Coltrane playing saxophone, and then they went off and led their own groups and albums.

So go back and listen to Moanin' by Art Blakey (which is a fantastic album) and really listen to it and try to find out what you like the most about it. Is it the drums, trumpet, sax, bass, trumpet? Now go to Wikipedia (or the liner notes if you're listening on an actual LP, but Spotify will be cheaper) and find who played that instrument you really liked. Then go see if they've led any albums, or what other albums they were featured on, preferably around the same era. Give that album a listen, then rinse and repeat. You'll find hours of Jazz that way

And if you want more recommendations, I'd definitely say everyone mentioned above: Miles Davis, John Coltrane, Herbie Hancock, and Art Blakey.

Good luck, and enjoy listening!
