The Post-Grunge band inherited the anxious, calm and introspective music style of typical Grunge music, and regarded it as a necessary element of Grunge art. Even in their low period, Post-Grunge bands maintained a very serious and sober attitude towards their own existence. In the end, the unique elements of Grunge music became an indispensable ingredient in the nature of orthodox music. Post-Grunge style influenced almost the entire mainstream mature heavy rock music of the 1990s. Although the music contains alternative elements, Post-Grunge is still a mainstream commercial music - its rich and flowing Grunge guitar playing makes the music beautiful and smooth and popular. Many bands are very similar in style but not identical; in addition to old grunge music, post-grunge also draws on early 1980s raucous pop, punk pop, revival ska, alternative metal and classical memorial rock and other musical styles. In addition, some weird Post-Grunge items are popular for their dark humor rather than low-key melancholy. Post-Grunge music surfaced soon after the old Grunge music was produced; the nirvana band, which represented the old Grunge style, entered its peak period in early 1992. Just a few years later, the Post-Grunge style bush band and candlebox band also gained popularity. A huge success. After the initial heyday of old grunge music passed, the post-grunge style began to rise, and a number of new bands emerged in the mid-to-late 1990s; some of them continued to be popular, while others were short-lived. To this day, the Post-Grunge style is still thriving, and creed and matchbox20 are the two most popular bands of this style in the United States.
