You're not likely to confuse these birds with The Byrds, but a charm of finches at a Massachusetts museum are showing they're not bad at guitar. Right now, at the Peabody Essex Museum in Salem, Massechusetts, visitors can catch FreePort [No. 007]: Céleste Boursier-Mougenot, an exhibit in which the French artist Céleste Boursier-Mougenot unleashes 70 Zebra Finches on a room containing 10 Gibson Les Paul electric guitars and four Thunderbird basses. Boursier-Mougenot, known for his avant-garde acoustic art, first installed this exhibit at London's Barbican gallery in 2010.The finches have free reign of the gallery space, temporarily dubbed "The Aviary," and play music by landing on the instruments, which are mounted horizontally like perches. (The museum currently employs a veterinarian and someone to clean up the inevitable bird poop.) These finches play music that's more electro-ambient than rock-'n-roll, and you can hear a little bit of their music in this radio story on WBUR. For a look at the installation, check out the gallery above.
