An interesting collaboration between eye and ear is taking place at Bridget Donhahue Gallery this month. Chicago-based visual artist Lisa Alvarado has linked a series of large multi-colored banners to her performance as harmonicist in the experimental Afro-Jazz band “Natural Information Society”. Used as set backgrounds to the band’s concerts, the banners serve as important focal points to the music. Bold colors, a free-standing hanging method, and vibrant geometric patterns remind of Aztec tribal art – combine them with the enchanting, hypnotic music that is wafting through the gallery, and you have a whole new artform indeed. A live performance schedule is posted on the gallery’s website. At Bridget Donahue through May 21.
