I bought the three-disc Duke Ellington Live and Rare box for under $7, which will complement the Centennial box.
As part of the current Qobuz sale I went on a HighNote splurge and bought:
Woody Shaw - Live, Volumes 1-4
Woody Shaw and Louis Hayes - The Tour, Volumes 1 & 2
Larry Willis - I Fall in Love Too Easily ( The Final Session at Rudy Van Gelder's)
Gene Ludwig-Pat Martino Trio - Young Guns
Lester Young - Pres in Europe
Charlie Ventura and Bill Harris - Live at the Three Deuces, Volumes 1 and 2
Hot Lips Page - After Hours in Harlem
For 12 CD-quality downloads, I paid $33.25. I gave up on trying to choose between those Woody Shaw live albums and simply bought them all.
