METI 0–1 // [AV Composition VI] (2021)
METI 0–1 is a time-based audiovisual composition by Pitch Shifting (Grgur Savić / Sanja Star).
The work is conceptually based on METI (Messaging to Extraterrestrial Intelligence) and SETI (Search for Extraterrestrial Intelligence), two scientific frameworks concerned with the detection and transmission of signals beyond Earth. METI focuses on the intentional construction and transmission of messages into space, while SETI investigates received signals and potential evidence of extraterrestrial communication.
The piece translates these ideas into an audiovisual composition structured through signal-like transformations between sound and image, where audiovisual material operates as a speculative communication system.

Hyksos Talks // [AV Composition VIII] (2022)
Hyksos Talks is a time-based audiovisual composition by Pitch Shifting (Grgur Savić / Sanja Star).
Length: 1:41 min
Medium: mixed media, experimental video and sound
The piece draws inspiration from ancient Egypt, exploring a speculative imagining of the Hyksos period—when foreign rulers governed Egypt, leaving much of their history uncertain. It investigates the intersection of past and future as coexisting points in time.
Through system-based sound processes and data-driven visual structures, audio dynamics inform live digital animation and compositional transformations. The work foregrounds the uncertainty inherent in communication, reflecting on how signals, time, and context shape perception.

tMspcshiFt // [AV Composition V] (2020)
tMspcshiFt is a time-based audiovisual composition by Pitch Shifting (Grgur Savić / Sanja Star).
Length: 2:57 min
Medium: mixed media, experimental video and sound
The work is inspired by the 2019 experiments of scientists attempting to open portals to multiple universes. It explores the conceptual dynamics of time travel, alternative histories, and the consequences of interventions in past events. By translating these ideas into audiovisual form, the piece investigates how alternative temporalities and potential realities intersect, overlap, and collapse.

pre√~µ // [AV Composition 0] (2019)
pre√~µ is a time-based audiovisual work by Pitch Shifting (Grgur Savić / Sanja Star).
Length: 0:40 min
Medium: mixed media, experimental video with live performance sound
Inspired by the concept of the Holodeck (first appearing in Star Trek: Encounter at Farpoint, 1987), the piece imagines a holographic environment where space, sound, and visual media converge. Live performance sound is integrated with abstract visuals to create a compact, immersive audiovisual experiment.

(AV Rework II), Na-TraJa201EXp’ (2019)
Length: 2:19 min
Medium: mixed media, experimental video with live performance sound
Na-TraJa201EXp’ is a time-based audiovisual work by Pitch Shifting (Grgur Savić / Sanja Star). The piece explores the relationship between rhythm, pitch, and perception. Changes in temporal periodicity are interpreted as melodic transformations, with inner subdivisions of the basic period forming micro-rhythmic “partials” that shape the sonic structure.
The work evokes a cosmic, embodied perspective: inspired by the notion of Nataraja, the dancer, the performance reflects the interconnectedness of the body, the stars, and the universe, presenting an audiovisual meditation on the dance of matter and perception.

Length: 0:55 min
Medium: mixed media, experimental video with live performance sound
Ex-ct4 is a time-based audiovisual work by Pitch Shifting (Grgur Savić / Sanja Star). The piece explores the perception of rhythm and pitch, where variations in temporal periodicity are interpreted as melodic transformations. Micro-rhythmic subdivisions of the fundamental period—“partials”—structure the sonic landscape, creating an intricate interplay of time and tone.
The work evokes a cosmic, embodied perspective, inspired by the Nataraja, the cosmic dancer. Sound and image reflect the interconnection of body, stars, and universe, presenting a meditation on the dance of matter, energy, and perception.

CatIII ILS (2020)
Length: 3:33 min
Medium: mixed media, experimental video + sound
CatIII ILS is a time-based audiovisual work by Pitch Shifting (Grgur Savić / Sanja Star). The piece draws inspiration from the Instrument Landing System (ILS), which guides aircraft safely during conditions of zero visibility. Translating principles of precision, guidance, and signal interaction into a sonic and visual framework, the work explores the interplay of radio-like signals, light, and spatial perception in immersive audiovisual form.

FRB-07 // (AV Composition III)
Length: 4:11 min.
Medium: mixed media, experimental video + sound
Year: 2020
Synopsis:
FRB-07 is an artistic interpretation of Fast Radio Bursts (FRBs). These enigmatic signals, originating from rapidly rotating celestial bodies such as magnetars or quasars, have been hypothesized to include extraterrestrial sources. Initially attributed to singular cosmic events—like black hole formation from neutron star collisions—the recurrence of these bursts challenges conventional explanations. Other theories suggest interactions with black holes, but observational evidence remains inconclusive. FRB-07 reflects on these uncertainties, translating astrophysical phenomena into immersive audiovisual experiences. The piece transforms radio-frequency patterns into visual and sonic narratives, highlighting the mystery, repetition, and complexity of cosmic signals.

NANITE // (AV composition II)
Length: 1:34 min
Medium: mixed media, experimental video + sound
Year: 2020
Synopsis:
NANITE explores the concept of molecular machines, or nanomachines—microscopic components that produce quasi-mechanical movements in response to specific stimuli. In biological systems, macromolecular machines carry out essential processes such as DNA replication and ATP synthesis. This work extends the concept to speculative technology, imagining how microscopic agents could function in complex systems.
Drawing inspiration from the Star Trek universe, the piece references the Borg: cybernetic organisms linked in a collective consciousness. Through assimilation, the Borg integrate the technology and knowledge of other species, forcibly transforming individuals into cybernetic drones. NANITE interprets these ideas through experimental audiovisual forms, creating a synthesis of scientific inquiry, speculative fiction, and immersive sound-visual experience.
