LA Radio: Classic Rock KLOS Leaps Into Top 10

In May 2025, Meruelo Media’s Classic Rock station 95.5 KLOS in Los Angeles achieved a 4.1 share in the Nielsen Audio ratings for listeners aged 6+, marking its highest performance since Fall 1991. 

This significant milestone was highlighted by the station’s strong programming and strategic investments in understanding Southern California’s rock audience preferences. The morning show, Heidi & Frank, led the ratings, securing the #1 spot for Adults 25-54 and #2 overall for listeners 6+ in its time slot. 

The new afternoon host, Nik Carter, also performed well, placing second in his time slot for Men 25-54. Meruelo Media’s President, Tomas Trujillo, and Vice President of Programming, Pio Ferro, credited the success to the team’s dedication and KLOS’s legacy as a premier rock station. 

The station’s evolved music selection, blending classic rock with tracks from the ‘80s, ‘90s, and beyond, contributed to its broad appeal.
