Five teenagers from Sarasota, Florida, are making music from garbage. The Garbage-Men band’s instruments are made from old things. The guitars are boxes. The horn (喇叭) is made from pipes . The keyboard is formed from old bottles.

The band started about two years ago. Jack, who was in eighth grade at the time, decided to make a homemade guitar. After some hard work, he ended up building it from a cereal box, a big ruler and some little sticks. After Jack showed his guitar to his friend Ollie, Ollie had the idea to make a band using other homemade instruments as a way to suggest people recycle old things. “We want to show people there is more to recycling than throwing things away in the rubbish box,” Jack, 16, told TFK. “You can actually recycle old things.”

Ollie, 15, plays the drums made from rubbish cans. Evan, 14, plays the guitar; Harrison, 15, plays the horns and the violin; and Austin, 16, plays the keyboard. They make up the band The Garbage-Men and play at local parties around. They wand to help people get interested in recycling old things. “Music is a really good way to get a good message across to people because it’s really easy for people to understand,” Jack says. Their instruments may be garbage, but their message isn’t.
