Back catalogue: Progressive Rock

Review: A treat for Pink Floyd fans, as recordings of two legendary concerts from 1969 - sneakily captured by members of the audience - are bundled together on one must-check CD. The first seven tracks showcase a portion of the legendary band's distinctively psychedelic performance at Plumpton Racecourse, Sussex (then host to the 'National Jazz and Blues Festival'), offering up twisted, elongated takes on early material (including 'Set The Controls for the Heart of the Sun' and a fine medley known as 'The Journey'. The final four tracks were recorded in Port Talbot and include breathtakingly brilliant, jammed-out interpretations of 'Careful With That Axe Eugene' and the pinnacle of psychedelic-era Floyd, 'Interstellar Overdrive'.

Review: The newly re-mastered release of Pink Floyd's legendary Pompeii performance from 1972 - released as a film initially and recorded without an audience - immerses the listener in the eerie grandeur of the ancient Roman amphitheatre. Steven Wilson, in charge of reworking the audio, breathes fresh life into the familiar, giving tracks like 'Echoes Part 1' and 'Careful With That Axe, Eugene' a heightened sense of space and detail. The alternate take of 'Careful With That Axe, Eugene' and the unedited 'A Saucerful of Secrets' show the band's ever-evolving approach at this most productive stage in their career. A raw, expansive reflection of Pink Floyd's creative journey as they morphed from psychedelic garage stars to prog rock giants.

Review: Phaedra is the fifth studio album by German electronic group Tangerine Dream, recorded in November 1973 at The Manor in Shipton-on-Cherwell, England, and released in 1974 through Virgin. An icier, tempoless departure for a band otherwise better recognised for their sequencer-led, soundtrack-bred sound, this was a hidden moulin for frost-drone fanatics, and a deviant pupil of the otherwise strict Berlin School. Despite receiving little to no airplay, Phaedra gained significant traction through word of mouth when it was released by a rather more hippified Richard Branson's fledgling Virgin label, eventually reaching number 15 on the UK Albums Chart and remaining on the charts for 15 weeks. Its long-form pieces, such as 'Sequent C' and 'Mysterious Semblance At The Strand Of Nightmares', represent an indifference to constraints of timing, instead washing over the ears as diachronic, swirling, crisp ice ambient smirrs.
