in late 2004, there were plans for krwp to switch frequencies 103.7 fm, or otherwise launch a simulcast with another station with the objective of providing better coverage in houston. at the same time, houston's heritage rock station, klol, dumped its rock format after 34 years in favor of a hurban (hispanic urban) format. on january 27, 2005, under new management, krwp inherited the former klol format of album-oriented rock (aor) and flipped to kiol as rock 97.5. the format change was headed by former klol personality jim pruett and program director/jock pat fant (who assumed market manager for cumulus houston as a result) in response to heavy outcry from misplaced klol listeners. the first song played on "rock 97.5" was "for those about to rock (we salute you)" by ac/dc.
