Disco's decline in popularity after Disco Demolition Night was rapid. On July 21, 1979, the top six records on the U.S. music charts were disco songs. By September 22, there were no disco songs in the US Top 10 chart, with the exception of Herb Alpert's instrumental "Rise," a smooth jazz composition with some disco overtones. Some in the media, in celebratory tones, declared disco "dead" and rock revived. Karen Mixon Cook, the first female disco DJ, stated that people still pause every July 12 for a moment of silence in honor of disco. Dahl stated in a 2004 interview that disco was "probably on its way out the time. But I think it Demolition Night hastened its demise".
