Ziggo is the largest cable TV company in the Netherlands. Last year, it ventured into the streaming music business by launching a service called Ziggo Muziek. Dutch creative agency Cape Rock created a visual identity for the brand built around a frequency bar that extends from the Ziggo logo. (The service itself doesn't have a dedicated logo per se.)
These frequency bars are used in several different ways. One video sequence can be adapted to include different artists. It also appears in the opening for a weekly top 20 chart of popular music videos.
