ISKC Rock Radio XXL

ISKC Rock Radio XXL is a Netherlands-based internet radio station broadcasting from Rotterdam, in the province of South Holland, that focuses on deep cuts and extended progressive rock tracks from a broad range of bands and artists. It is one of several niche channels operated by the ISKC Radio Group, a non-commercial network dedicated to various forms of rock and metal music. The station caters especially to listeners who enjoy complex, long‑form rock music rather than short singles. The “XXL” in its name refers to the station’s unique programming niche: it exclusively plays progressive rock songs that are longer than 9 minutes. This radio station focuses on long-form “epics,” including multi-part suites, extended live versions, and complex compositions.
