Dan Senn's International Space Band performs pieces on aluminium-cast lids from ordinary pans. The American composer and soundartist Dan Senn is the inventor of these musical instruments. He performs pieces with the instruments every where he goes; in different cities he forms a sponteneous musical band to walk the streets or to investigate the acoustics of a building. This goes by the name International Space Band. Petra and Mario had the pleasure of performing the piece twice: in Den Bosch and in Prague, and because of their enthusiasm, Dan sent over 12 lydes (as he calls them) to Eindhoven, where Petra and Mario started Dan Senn's International Space Band, a group consisting of 12, mostly untrained musicians who just love the sound.
