Who is jazz fan, has already heard the names of both artists safely. But I was new that they have already played together. So when I saw this album, I bought it immediately. It exceeded my expectations, which were certainly ambitious, without problems. The album is the recording of a live concert, where not only the pieces but also the humorous announcements are included. Chick Corea ingenious jazz improvisations on the piano are accompanied by the vocal artistry McFerrin (known by 'Do not Worry, Be Happy') - a lot of scratchy noises that I could imitate impossible - and singing, the text of which has been locally changed in a funny way (eg when classic 'Autumn Leaves'). The songs have as much pep that audiences sometimes as 3. artist intervenes (eg 'Even From Me'). So if you like jazz and humor has, which is well served with this CD -> So buy !!
