In in blik, instead of musicians, five tin can towers are performing. The tin cans are humming softly, singing aloud or just breathing . At certain times though, they also try to break out of their tin cans: they start to shake and move, sounding now like percussion instruments. They shake till they drop apart, and nothing more than some ordinary tin cans are left.
Tin cans and metal plates, placed on tactile transducers, are producing the sounds. Tactile transducers function as loudspeakers without membranes. They vibrate depending on the electric current they receive, but, contrary to loudspeakers with membranes, they barely produce any sound. They transmit their vibrations directly to the tin cans placed upon them. The tin cans amplify these vibrations and make them audible. Every tin can tower will amplify these vibrations differently, depending on the way the tin cans are placed upon each other and the height of each tower. Each tin can tower will resonate at certain frequencies while damping others. The construction of the tin can towers is "tuned" in a way which could be compared to the building process of a conventional musical instrument. The amount of tin cans on a tactile transducer and the form of the tin cans (if they are opened or closed on top) shapes the final sound result.
