Green Day was one of the most popular and influential bands of the 90s and early 2000s. Their fun, high-energy music helped bring punk into the mainstream. Throughout this 5-day camp, weâll explore hits from some of their most popular albums, such as âDookie,â âWarning,â âInsomniac,â âAmerican Idiotâ and beyond. At the end of the week, students will put on a live performance. Great for students 7-18 years of age who have had some previous instruction.
