This was the first jazz album that I ever bought and not knowing anything about the style, I didn't know what to expect. To say I was pleasantly surprised would be a complete understatement but to say that since that day the only music I've listened to has been jazz (be it Benny Goodman or Jaco Pastorius!) would be about right. From the opening bars of "So What" you know that you're listening to a masterpiece and a piece of history that could never be repeated. The 50 minutes just disappear and I guarantee when it's over you will go and press play again - I have been listening to it for years and I'm still finding new bits that I've missed! There is not one fault to be found with this album - it is pretty perfect...As albums go!
