In this lavishly illustrated book, the words to Bobby McFerrin's brilliant Don't Worry, Be Happy are married to the art of Alexander Calder. Surely one of the seminal songs of this generation, McFerrin's joyous anthem has sold over twenty million copies and been a #1 hit in virtually every industrial nation in the world. The pure lines of Calder's art echo the simplicity of McFerrin's song. The idea - Don't Worry, Be Happy - illuminates almost every piece of art that Alexander Calder ever created, from his fanciful hanging mobiles and his circus characters fashioned from wood, wire, fabric, rubber, and leather to his tin sculptures cut from everyday cans. It is impossible not to smile when looking at a Calder mobile where movement, form, and materials combine to delight and surprise. In the same way, Bobby McFerrin's exultant voice and pure melodies remind us that joy and pleasure are ours for the taking. Both artists celebrate the bliss of everyday life and the happiness that is to be discovered everywhere.
