iROCK 103.9 KCJF traces its DNA back from Foo Fighters and Pearl Jam to AC/DC and Led Zeppelin. It reaches forward from The Red Hot Chili Peppers and Nirvana to Linkin Park and Three Days Grace. DNA really is the perfect word to describe the thread that binds together iROCK’s tremendous variety in texture and era with the strength and balance of familiarity. This is ROCK radio… Version 6.0!
