PXR5 is the ninth studio album by Hawkwind, released in 1979. It reached No. 59 on the UK album charts.
The album was recorded and mixed at Rockfield Studios in January and February 1978. "Uncle Sam's on Mars", "Robot" and "High Rise" were originally recorded on the preceding UK tour but were partly overdubbed in the studio, particularly Robert Calvert's double-tracked vocals. "Infinity" and "Life Form" were originally to have been part of a solo album Dave Brock was working on.
After the album was recorded and mixed, the band split up during a US tour in March when Simon House left to join David Bowie's band and Robert Calvert suffered a bout of clinical depression. With the band in temporary hiatus and no pending promotional tour, the album's release was shelved.
The band re-emerged in mid-1978 as the Hawklords to record the 25 Years On album. Two tracks were released as singles, "Psi Power" and "25 Years", which featured "Death Trap" and "PXR5" respectively on their B-sides. The PXR5 album was eventually released on 15 June 1979, and the cryptic message on the cover "This is the last but one" refers to the fact that it was recorded prior to 25 Years On.
Two years ago our nova-drive failed and we drifted in space
But now repaired our motors run to continue the race
Three of our crew who were with us then did not survive
Their life supports could not take the strain and so they died
And so we search until we find the answers that we left
behind, and we go from star to star to find the dream
And we will pursue the race that made us journey into space
and led us to become a seed of life, PXR5, PXR5
Robots call, but we don't answer to their wail
Computers hum and bright lights flash to no avail
The course has been set for us to go in light years past
Outlaws of time, visions of an ancient cast
And so we search until we find the answers that we left
behind, and we go from star to star to find the dream
And we will pursue the race that made us outlaws of this space
