Bash the Trash weaves together science, music and environmental awareness and offers programs and events for museums, performing art centers and more.

For over 25 years Bash the Trash has been building, performing and educating with musical instruments made from recycled and reused materials. We demonstrate how science can transform even the simplest stuff into cool-sounding instruments, and how you can make your own! 

Directed by the husband-and-wife creative team of John Bertles and Carina Piaggio, Bash the Trash features a national roster of over 30 musicians and teaching artists, weaving together science, music and environmental awareness. 

History of Bash the Trash

Founded in 1988 as The Experimental Orchestra, BTT originally provided classroom workshops and residencies under the umbrella of cultural institutions such as Carnegie Hall, the Guggenheim Museum and New York Philharmonic. 

As a separate entity BTT began providing larger performances in 1991 which brought about the name change to Bash the Trash, which became a registered trademark in 1998. By that time BTT was providing roughly sixty performances a year as well as workshops to students around the NY-NJ-CT area and beyond, plus professional development and consulting services.  

In 2008 we reorganized as Bash the Trash Environmental Arts LLC, and began to offer environmental programming and performances across the United States, with regional performers based in Massachusetts, California, Hawaii, West Virginia, Michigan and Nebraska. BTT has also performed internationally in Argentina and Canada. 

Bash the Trash currently reaches about 60,000 students, teachers and adults per year through performances, workshops, festivals, professional development sessions and other events. Our roster of teaching artists and performers includes musicians, dancers, storytellers, theater artists and electronic media artists.
