Tuba Skinny with Shaye Cohn playing Piano - "Blue and Lonesome" - Spott...

Go to Youtube and read the comments about Shaye Cohn. This answers a lot about why this band is so good.
  According to the comments in the video shown above Shaye Cohn is the granddaughter of jazz musician Al Cohn. And she plays 4  instruments.  She is the driving force behind this band and now I know why they are so good. And Erika Lewis is something special as a jazz/blues singer.
