Merely approaching the field of art involving modifying and inventing instruments gives us a pleasant anxiety. There's so much out there! Violins that play records. Artists that play buildings. Beats that play artists. Seems like magic happens when these mediums of creation entwine, but these few sound and look so amazing, it's positively seductive. From replicas of Hieronymus Bosch's surreal harp-lutes to Pierre Bastien's tiny, mechanical orchestras, here are just a few functioning, artist-created instruments that we'd love to strum, bang, and play.
