Having completed the American leg of their tour in support of their new album
Relaxer, alt-J has arrived in Europe for theatre and arena dates — and a full
production inventory that includes multiples of GLP’s award-winning X4 Bar 20s.

Liteup Events supplied the core control package for lighting and video worldwide and
the entire production in Europe while Upstaging provided the lighting inventory in the
States. Marc Callaghan, who co-founded Liteup Events with Kris Box, has been
working as crew chief on the tour, while the task of creating the visual impact, has
been entrusted to the team from US based FragmentNine (Jeremy Lechterman and
Jackson Gallagher) — the former focusing on the lighting, with his partner
masterminding the video/media.

Although the company was only set up two years ago, Lechterman and Gallagher have
been working together since their days at Carnegie Mellon University before bringing
their expertise with theatrical design and storytelling to the concert sector. Currently,
on tour with Icelandic act Asgeir, they have already provided technical services to a
raft of other leading artists.

Jeremy Lechterman says he always sensed the X4 Bars would be a great tool once
they found the right application. He explained that they were planned into the design
“as soon as the immersive digital forest concept came about. We knew we wanted a
vertical batten behind the LED surfaces, and when compared to other linear tilting
battens, the X4 Bar won due to its pixel density and output.

In fact, they had originally used them on a Spring date for alt-J. “We were very happy
with the result using them at that show,’ the LD confirmed. “No other batten can
create as uniform a light curtain as the X4 Bar, nor can it throw a beam as far as the
X4 Bar. We use them primarily to create large curtains of light emanating from the
video wall, which could not be achieved with any other product that we are aware of.’

Run in 88-channel mode, the X4 Bars really become a feature midway through the
set, immersing the band in ominous green and yellow swathes of light during Gospel
of John Hurt.

The fixtures are fully mapped in a d3 server, with an ArtNet merge back into the
grandMA desk. “They are used in more than half the songs and are fully controlled
via video aside from their tilt,’ Lechterman confirms. “The most successful usage of
them is playing content on our Vanish walls and then duplicating the content again on
the X4 Bars, so it looks like the video is pushing out in 3D space behind the band —
volumetric video! This is then reinforced again by the screens in between the band,
making a truly immersive environment.’

Overall, he says, the X4 Bars have more than delivered the expectation. “We love
them for their speed and reliability. With 186 fixtures from various suppliers travelling
across several continents so far, we’ve only had two fixtures go down in four months
of touring. We are well happy with that.’
