The vibraphone consists of tuned metal bars which the player hits with mallets. It is common in classical music, but especially prevalent in jazz and there is no-one better on 'vibes' than Milt Jackson. Here he is with Modern Jazz Quartet, the group founded and led by pianist John Lewis and in which Milt spent much of his career.

So shut down the laptop, kick off your shoes and let John and Milt sink you in to summer. They start slow. Then get a little less slow. But never get too fast.
