Solstice is a work by Iran Sanadzadeh and Luna Valentin. Premiered on the solstice at the Centre for Computer Research in Music and Acoustics, Stanford University, the concert took place with the sunset on the longest day in the northern hemisphere. This piece brings together Iran’s extensive work with gestural controllers in performance (namely the pressure-sensitive floors), and object percussion, with Luna’s expertise in spatial audio in performance and her unique performance voice on the contrabass. The instruments involved all have a personal relationship with the performers; Luna designed and built the contrabass she performs with, and has designed the technology to use virtual acoustics as a performance tool, making reverb an instrumental part of the performance. Iran’s collection of sound objects, along with new friends found around the studio, were suspended in a ‘sound catcher’ made with Luna, and become the centre of the two characters’ interaction in the piece. Theatrical in nature, this work uses ropes to extend the bodies of the musicians while constraining them, allowing for new engagement with sound and bodies by changing the weightlessness possible by suspension. This work invokes narratives of interaction and conflict, embodied by the musicians, woven in a rich tapestry of sounds that interact. From the spring used to make reverb, to performing on the contrabass and controlling its effects with the floors, the elements of the piece weave together. Warm sonic palettes are created using unlikely sounds, and experimentalism is created in tune with connection in this work.
