Restored to 4K quality from the original negatives : 1971 Pink Floyd at IMAX
 

[Pink Floyd to rerelease restored 1972 Pompeii
concert film in Imax
Iconic performance amid Roman antiquity has
been restored from original negatives,
with a soundtrack newly mixed
by prog star Steven Wilson]



[One of the most distinctive concert films
in rock history, Pink Floyd at Pompeii,
is to be rereleased in cinemas – including
in Imax format – and have its first
soundtrack release.
Filmed in 1971 and released the following year,
the film (previously titled Pink Floyd: Live at Pompeii)
captures the band shortly before
The Dark Side of the Moon ushered in
their most commercially successful phase.
It will be in cinemas worldwide on 24 April.

Forgoing the usual concert film format,
director Adrian Maben decided to have
the group perform without an audience,
in the eerily deserted Roman amphitheatre
in Pompeii: the first band to play there.]

It's a favourite concert film of mine.
