Have you ever wondered how off-key you are while singing in the shower? Or if your Bob Dylan albums really sound better on vinyl? Or why certain songs make you cry? Now, scientist and musician John Powell invites you on an entertaining journey through the world of music.

The great unknown of the Southwest is conquered by a one-armed man and his crew of adventurers, placing the Colorado River and the Grand Canyon on the map of the American continent. It is a journey no human being had ever made before. Dangerous rapids, narrow canyon walls offering no escape, terrifying river waterfalls, capsized boats, near drowning, lost equipment and disillusioned men are dramatically described by John Wesley Powell, leader of this adventurous party.
