On Saturday, Aug. 15, Consortium of Genius returns to Southport Hall in Jefferson for Drumbot’s 30th Birthday, a celebration honoring the wisecracking robotic drummer who’s been keeping time—and cracking jokes—since the mid-1990s. For more than three decades, Consortium of Genius has delighted audiences with its eccentric blend of rock, comedy and theatrical storytelling, led by the delightfully unhinged mad scientist Milo T. Pinkerton III. Advance tickets are $10, and fans can expect birthday cake, plenty of COG-style surprises and, naturally, a toast to Drumbot’s milestone birthday. Founded with the mission of blending rock music with theatrical performance, Consortium of Genius has built a devoted following through its imaginative stage shows, memorable characters and offbeat sense of humor. If you’re looking for an evening that’s equal parts rock show, sci-fi comedy and birthday party, Drumbot’s 30th promises to deliver.
