I just can find the words to express my gratitude for all this knowledge shared,
you guys are great!
thank you for making myself in a more sophisticated audiophile i guess at least on music taste.
happy holidays I am listening also Jazz 88 from Newark NJ, wow, a super choice to learn.

Someday My Prince Will Come Analogue Productions.

Charles Mingus Ah Um
Miles Davis Kind Of Blue
Patricia Barber Cafe Blue
Oscar Peterson Night Train
Miles Davis Birth Of The Cool
Bela Fleck and The Flecktones Little Worlds
Thelonius Monk Straight No Chaser
Return To Forever Romantic Warrior
John Coltrane A Love Supreme
Miles Davis Bitches Brew

It shocks me that a long list of audionuts would reply to this question without mentioning Louis Armstrong Plays King Oliver. This is probably the demo LP and song(St. James Infirmary) that I've heard offered as a reference by more audiophiles and jazz fans than most of the others combined.

From all the recommendations I have to agree that the best vocals LPs to start with are:
Johnny Hartman & John Coltrane
Ella Fitzgerald - "Clap Hands Here Comes Charlie"

Another that I'd add is Billie Holiday -Songs For Distingue Lovers Cheers,
