Two bands that were important to the Twin Cities punk scene are:
1. **Hüsker Dü:** Hüsker Dü was a punk rock band formed in Minneapolis, Minnesota, in the late 1970s. They were known for their fast and melodic punk sound and played a significant role in shaping the punk and alternative music scene, not only in the Twin Cities but also on a national scale.
2. **The Replacements:** The Replacements were another influential punk and alternative rock band from Minneapolis. Formed in the late 1970s, they blended punk rock with elements of alternative and indie rock. Their music and rebellious attitude made them an essential part of the Twin Cities' punk and music culture.
Both of these bands contributed to the vibrant punk and alternative music scene in the Twin Cities during the 1980s and had a lasting impact on the broader music landscape.
