Pitch Shifting is an experimental audio-visual collaboration by Sanja Star (HR/DE) and Grgur Savić (HR/DE), rooted in improvisation, exploration, and collaboration. Since 2019, they have been shaping fluid, real-time performances where electro-acoustic sound and dynamic visuals dissolve boundaries between mediums.
Their work thrives on dialogue—between acoustic and electronic, structure and spontaneity—creating ever-evolving performances through live improvisation. Expanding beyond the duo, Pitch Shifting collaborates with artists across disciplines.

OUTBOX: A Sonic Journey through Interaction and Visualization (EXPERIMENTS IN PERFORMANCE)
“In the urban white box, Pitch Shifting finds an experimental space, a retreat and also a space of contemplation for their audiovisual compositions.” Pitch Shifting
OUTBOX is an ongoing collaborative performance that explores the intersection of sound, music, and visual art through improvisation and experimentation. Experimental musician Savic and transmedia artist Star create a dynamic, shifting environment using a variety of instruments, amplified objects, electronics, generative soundscapes, and live visuals. The performance unfolds in real time, where sound and image interact, constantly reshaping the experience. By expanding beyond conventional limits, OUTBOX invites the audience into a space where the lines between media blur and new forms of expression emerge.

Seas of Mintaka: Navigating the cosmic soundscape
Seas of Mintaka draws its inspiration from the stars, with a particular focus on Mintaka, a key star in the Orion constellation. Symbolizing exploration and mystery, Mintaka serves as a metaphor for the journey embarked upon in this performance—an odyssey through both sound and visual experience.
Guided by Grgur Savic and Sanja Star, the audience is led through the cosmic “seas” of Mintaka, where each sonic wave is transformed into evocative, abstract visuals. Both artists engage deeply with frequency in their respective practices, creating an environment that reflects the complexities of the universe and its infinite phenomena.
Savic weaves an experimental blend of classical, IDM, and electroacoustic music, punctuated by moments of noise and dissonance, evoking the vast depths of space and the mysterious forces that shape the cosmos. In parallel, Star’s abstract visuals—crafted from digital motion collage, 3D art, coding, and live animation—respond to and mirror the soundscape, creating an immersive, audio-reactive visual experience.
Seas of Mintaka becomes a journey through unknown realms, where sound and image are navigational tools, guiding the audience into the uncharted territory of the cosmic unknown. Through the performance, each note and visual form becomes a step into the vastness of the universe, inviting reflection on the infinite and the unknown.

INFILTRATION: A SONIC AND VISUAL EXPLORATION OF THE UNKNOWN
INFILTRATION unfolds as a sensory encounter, where live sound manipulation and abstract visual art converge to explore themes of intrusion, adaptation, and transformation. Drawing from the mysteries of deep space and the unknown, the performance constructs an ephemeral environment in which shifting sonic architectures and dynamic 3D animation form a constantly evolving dialogue.
Savić extends the acoustic properties of the saxophone through real-time digital processing, distorting and reshaping its timbre into spectral, unfamiliar textures. These transformed sounds interact with Sanja Star’s 3D animations, where abstract forms materialize, dissolve, and collide within a landscape of shadow and illumination. The interplay between sound and image unfolds as a negotiation between presence and absence, evoking both dissonance and harmony.
Set in near-total darkness, the stage becomes a fluid perceptual space, punctuated by intentional light that reveals fleeting glimpses of movement and form. As sound and visuals evolve, the audience is invited into an altered sensory terrain, where the boundaries between the known and the unfamiliar remain in flux.
Neither fixed nor linear, INFILTRATION operates as an open-ended meditation on unseen forces—signals, transmissions, and imperceptible shifts that shape perception and experience. It is a reflective and transitory performance, where sound and image function as agents of transformation, dissolving the familiar and inviting contemplation of the unknown.
