1974 WLRS 102.3fm, Louisville KY, aired an album-oriented rock (AOR) format. The playlist of The Beatles, The Rolling Stones, The Who and Creedence Clearwater Revival brought WLRS top ratings in 1978. WLRS began using a "walrus" as the station mascot in the 1970s. The spelling of walrus roughly translated to the station's call letters. 1984, the station switched to a hybrid format of album rock hits and Top 40/CHR songs as "The Flamethrowing LRS 102". 1991, WLRS flipped to adult contemporary music as "Mix 102".
