Readers' Poll: The 10 Best Opening Acts in Rock History

This 1972 American tour captured two of the greatest live acts in history at their absolute creative peaks. The Stones were touring in support of Exile on Main St., while Wonder had just dropped Music of My Mind and was months away from the release of Talking Book. Rock audiences weren't very familiar with Wonder's genius at this point, but this tour changed all that. Some shows ended with an amazing medley of "Uptight (Everything's Alright)" and "(I Can't Get No) Satisfaction," and the two songs (released just months apart in 1965) blended perfectly into one another. Check out a video of the medley here.
