A related project titled Blues Birds was also presented at Glendale, AZ’s Jazz and Blues Festival in 2010. Bird Song Sing is an interactive installation that invites visitors to take on the identity of twittering birds. Large bird masks are mounted on microphone stands on a small platform. Visitors can walk up to a mask, and speak, whistle, and sing. The participants’ voices are picked up my microphones inside the bird-masks, and and transformed into birdcalls, which are played from speakers hidden in the platform.
