Tunnel Visions: Array transformed the tunnel into an audio-visual performance space
UK - Part of this year’s Barbican OpenFest saw a major new Culture Mile light and sound installation take place in the Beech Street tunnel, opposite Barbican Underground. Culture Mile presented Tunnel Visions: Array which transformed the tunnel into an audio-visual performance space combining cutting-edge projection and sound technology with the Barbican’s distinctive brutalist architecture.
Created by Tony Award-winning artists 59 Productions led by director Richard Slaney, co-produced with the Barbican, and with music by composer/conductor Esa-Pekka Salonen, Tony and Olivier Award-winning sound designer Gareth Fry was commissioned to create a multi-channel spatial sound design for the immersive multimedia art project, using TiMax SoundHub-S64 spatial audio matrix and playback engine.
TiMax directed the audio playback of 30 channels of audio stems and effects tracks from its on-board playback engine, including SMPTE timecode, making for quick and complex rendering of spatial pan effects, multitrack mix automation and precise synchronisation with visual content.
TiMax input parametric EQ proved invaluable for source sweetening of the multitrack audio stems derived from raw live microphone recordings of the composition piece. Salonen’s Karawane – written in 2014 – was previously recorded by the BBC Symphony Orchestra and Chorus in concert at the Barbican Hall as part of a BBC Total Immersion Day.
Using a dedicated SMPTE timecode track striped onto its internal SSD drive, TiMax controlled and synchronised a stack of Disguise video-mapping media servers. Forty projectors mounted on speaker towers distributed down the tunnel were arranged in a crossfire configuration to video-map every wall and ceiling surface. The end result was a single, vast 3D screen with abstract and dynamically-animated video art, synchronised to the music and TiMax immersive spatial events.
The full 70m length of the Beech Street Tunnel was covered by a distributed system of 40 individual Meyer UPJ active cabinets and 20 sub bass units. Individual outputs from TiMax were networked to these on a redundant Dante network then connected via four satellite Yamaha RIO32 breakout boxes.
The TiMax system was implemented and programmed in pre-production and on-site at the Barbican Beech Street tunnel by Out Board’s Robin Whittaker, as Gareth Fry was committed to tech rehearsals for the Broadway opening of Harry Potter and the Cursed Child.
Director, 59 Productions’ Richard Slaney, sums up, “TiMax created a fantastic audio experience for the thousands of patrons that visited Array during this year’s OpenFest, enabling the audience to fully immerse themselves in this unique, specially commissioned recording.”
