This final episode is a bit of a two-parter. Part one is Bob explaining the impact of, mostly, British rock stars and their crews invading tiny Marissa, Illinois to shop at Ye Old Music. In modern day terms imagine Carrie Underwood strolling into your local music store.    Part two ends 50 Years of Maximum Rock & Roll with a few stories from current Heil Sound employees who keep the fires burning for performers worldwide as they build incredible microphones for the next fifty years. It's all about people, isn't it? We think it is. The harvest and the feast. Enjoy.
