The album was made using the direct to disc recording method, in which recording tape is not used. This method requires that the group perform two 15-minute sides live in the studio with no overdubs. The recording is mixed live and transcribed to the master disc as it is being performed. This was a briefly popular format in the 1970s, and like all albums made this way, it was a limited edition, because only so many copies can be pressed from the master disc. The album was mostly instrumental, consisted of one piece on each side, and was issued on a small label called Labyrinth Records, catalogue number LBR-1001, which suggests it was likely the label's first release. It was well received by critics who compared the first side to a blend of Yes, King Crimson, and Lighthouse, while the second side took on a jazz feel, concluding with the sound of an unusual instrument: an alpha wave brain monitor plugged into a synthesizer, translating drummer Martin Deller's live brainwaves into a throbbing hum.
Artwork
The fantasy cover art by Paul Till shows a warrior gazing into a portal and seeing a green glowing vacuum tube in the foreground, superimposed over the warrior's face. The concept references the album's use of older, but not obsolete, and superior recording technologies: tube amplifiers, and the direct to disc recording process.
Editions and ''Head Room'' reissue
During the recording session, six takes were recorded for each side. The original edition uses take four on each side. The take number is determined by checking the side number suffix in the matrix numbers inscribed next to the run-out groove. Suffixes A4 and B4 indicate take four. This version was a limited edition of 20,000 copies. Some time after the original edition's release, several reissues appeared. One still has the original Direct to Disc title, but it has a different company name on the label: Kiras Music Works. Another edition changes the album title to Head Room, or perhaps Headroom. The title, which is also the title of the piece covering side one, is spelled as one word on the main track list printed on the inner gatefold cover, but as two words in the engineering credits and on the first edition's cream coloured label. Conversely, it is spelled as two words on the front cover of the later edition, but as one word on its black label, which has no label name. All editions continue to use the Labyrinth Records name and original catalogue number on the cover. These later editions use different takes of the track for side two. Takes one and two are known to exist. In an interview, Martin Deller suggested the later editions were not known to the band at the time:
"As far as the Direct to Disc goes there was a limited pressing of 20,000 copies and it sold out. However a local fan has collected a couple of copies of the album and I understand that they have different versions of each take on them! I have yet to check this out but if so there may be more available."
The claim that alternate takes of side one exist has not been confirmed, but the quote suggests Deller was uncertain of the details. A remastered edition of Direct to Disc was released by Esoteric Records on February 25, 2013.
Track listing
Descriptions are taken from the track list on the album cover. Timings are taken from the first edition's label, which uses take four of each side. Later editions have alternate takes of side two, and timings are not shown on the labels.
Side one
"Headroom" – 15:36
*"Tyra" – An introduction of the three musicians with bass guitar, bass pedals, drums and electric violin.
*"Reflections One" – A violin piece with light percussion, congas, bass guitar chording and bass pedals.
*"Reflections Two" – The same themes as "One", presented over a background of sequences, string synthesizer, and drums with violin, vocal, and synthesizer melodies.
*"Scarberia" – The drum solo emerges into an improvised synthesized drum, violin, bass guitar bridge. The piece concludes with a rock and roll song in 14/8.
Side two
"Border Crossing" – 15:24 – A composition drawing from rock, jazz, and classical influences.
*"The First Movement" – was inspired by Japanese haiku; a three line verse having a rhythmic cadence of 5/7/5.
*"The Second Movement" – is free of metre and tonal centre, and contrasts the first movement with a lack of structure.
*"The Third Movement" – is introduced by an ostinato sequencer bass line. An improvisation by all players over this pattern follows.
*"The Fourth Movement" – is in traditional song form with drums, violin, bass guitar and bass pedals. The piece concludes with added synthesizer environments of modulated noise and alpha brain wave control of an ARP 2500.
