I listened and I listened, then I listened some more; I never got tired of listening, and she never got tired of coming up with new ideas. We're talking primarily bass and piano, with 3 vocals out of 17 tracks; one where Mary Lou sings "My Mama Pinned a Rose On Me", she got a big kick out of that one.
Every tune affected me in different ways; after I found out "Dirge Blues" was written for President Kennedy, I began to hear it differently; it's a blues with the sad cadence of that flag draped coffin that was carried on a horse-drawn caisson to the U.S. Capitol to lie in State. That was a sad day that poor people will never forget.
The way she can go from blues to boogie, and back to blues, or blues and boogie at the same time, is absolutely amazing. While all great pianists stand out, every note of her's seem's to ring with "Here I am, Mary Lou Williams, the little girl whose Mama pinned a rose on her"; I mean she reminds me of no one I've ever heard before, or will hear after her.
I have no idea why I didn't discover her before now, or that I knew so little about her music, but I just forgave myself, because now I have her.
Enjoy the music.
