We all have at least one glaring omission. Mine is 'Fats Nararro'. I am in the process of correcting that omission.
Your comment on the technical aspect of Parker's recordings has some merit, but, unless you are in the Kind of Blue and Krall crowd, that is not a valid reason. If you are into 'audiophile' recordings of Jazz, you will always have glaring omissions.
Lastly, you seem to have a problem with a lot of the seminal figures in Jazz. Are you sure you are a Jazz lover?
Cheers
