Milton Jackson is one THE Jedi Masters of the vibes. I Growing up north of NYC, I had friends who stumbled upon Jackson practicing vibes on the street. "Bag's Groove" is not only Jackson's jam, but IMO one of the ultimate vibraphone songs. Also IMO, the ultimate version of "Bag's Groove" is from the album "The Prophet Speaks." https://youtu.be/He9DBg8ukR0
