I quickly decided not to be a completionist when it comes to jazz, theres just too much out there. What I have done though is to select a musician and stream all their albums, compilations and singles. Its a great way to see musicians sound develop (although it can obviously take weeks to get through all that stuff). So far this year I have listened to John Coltrane (82 albums, 32 compilations - 232 hours worth on comps) and Alice Coltrane (19 albums) fully. Im almost through all of Miles Davis' stuff as well. Lee Morgan is likely to be next. Its really fun.
