Rok, I've listened to all of Mary Lou's music that you have posted, and I found it to resonate with me in a fashion I don't quite understand; it's like a childhood memory that I can't quite recall, but it makes me feel good to try and think about it.
Even her versions of the most common tunes, like "My Blue Heaven", are so uniquely different, that they become brand new.
Mary Lou Williams has added much to my musical enjoyment.
