Sound Project

Pass and Gumina met in the 1960s when Gumina built Pass a small, portable amp. Although Gumina started his career as a musician, he entered the electronics business and made instruments. He recorded Sound Project with one of his inventions, a polycorus, which is similar to an accordion. He and Pass started the record label Polytone Records after Pablo Records, Pass's label, was sold.^[1]
