Club reopened under new ownership in 2017, after an extensive renovation. The tower apex once had "CNB" signs for a local bank that was formerly headquartered in the Penobscot Building. For approximately 20 years ending in 2009, the building was home to radio station WJLB and its well-known 80s DJ, The Electrifying Mojo, who broadcast his nightly visits over Detroit from his 'Mothership'''. The Electrifying Mojo is credited with exposing many Detroit Techno musicians to new audiences through his broadcasts. The Smart Detroit Conference Center occupies space on the 13th floor, and includes Class A conference, meeting, or convention space. The Wayne County Friend of the Court occupies floors between the sub-basement and eighth floor, making it the current largest tenant of the building.
