Topper invited me as a young entertainment rigger to consultant on a project that ultimately became my first permanent sound system install job. Probably the main reason I’m where I am in my installation career now. Certainly one of the first persons to spend the time necessary to explain about large speaker systems and such. We’ve worked together on quite a few projects since then and his referrals have kept me busy every since.
