@curiousjim - me too.
I was only one year old, but still, my father was hip to this, so not sure what he was thinking not taking his one year old to Bremen to see the Almighty. Monk was my gateway later.
I was actually listening to an original pressing of the Riverside Ellington cover album he did, and I fell in love ... again. I know it's a bit different, and one of a kind for several reasons, one being an entire album of covers of one musician - the only one Monk ever did, and rarely did covers at all as you know.
I believe I love it because it does not feel like a "tribute album" - it feels like a "reverential inventive interpretation" of a something deeper in Monk. It just flows so nicely that I smile the entire time.
I wonder why he did it? Anyone know? The story goes that when Riverside bought his contract from Prestige, they wanted a "mainstream" appeal LP from him to move product and his awareness.
However, Monk seems to really enjoy it versus a "run through and get it out" from the big bosses. Something says, to me, Monk knew exactly what he was doing.
Pettiford and Clarke of course provide the lineage.
