The first large public event at Opus 40 was a rainy evening show by Richie Havens, the rock great known for his riveting impromptu performance of “Freedom” at Woodstock in 1969. During his Opus 40 set a bolt of lightning crashed only 40 feet away, Havens would recall, and “I didn’t move, I just stayed there. People thought I was nuts.” When asked about Opus 40, Havens said, “I just has some kind of mystical thing. People who go there are drawn back there.”
