I mean, as a kid he heard Lester in KC, so he got Full Lester. Therein lies the difference.
The notion of Lester having a strong influence on the R & B players is hardly original with me, but it is underplayed in Jazz 101.

What holds up more is the notion of vertical bs horizontal, but that too has its limitations.
Ultimately, it's all speech.
