About 1998
In 1998, KROQ’s playlist thrived on a mix of alt-rock anthems and genre-blending hits, with Beastie Boys and Harvey Danger leading the charge. The swing revival from Cherry Poppin’ Daddies and The Brian Setzer Orchestra added a retro flair, while emerging acts like Eve 6 and The Offspring solidified the station’s role as a tastemaker in late 90s alternative music.
