Since Bassmen are primarily sidemen, except for OP and Mingus, their best work can be found on records headed by others. For example Milt Hintons best work, in my opinion, is on "Heavy Soul" with Ike Quebec.

They made this record when Ike was dying and they knew it, hence the title "Heavy Soul". Milt Hinton's bass contributes so very much to this cut; but all of them played their hearts out on this album.
According to Frogman, Duke Ellington's bassist, Jimmy Blanton was very influential. Also Ray Brown, Paul Chambers, Milt Hinton, Charles Mingus, Wilbur Ware and, Oscar Pettiford. LaFaro was a pivotal figure in the bass world but hardly the first important bass player.
Jafant, perhaps you can find Jimmy Blanton's best work. Wilbur Ware is another bassist I don't think we've explored.
Enjoy the music.
