Rock Spectrum

Pretty much every album put out by London’s KPM Music under their “1000 Series” featured the same dark green cover with the company logo un the upper right hand cover — a generic branding that latter-day cratediggers made iconic. And while a lot of their albums are scattershot listening experiences, this one jams all the way through, and not just with lighthearted synth kitsch. You could single out this 1975 record for “Confunktion” alone — a lurching, maniacal, feedback-apocalypse-coda-sporting dirtbag symphony by bassist Dave Richmond, a piece that’s been sampled by Madlib and featured in at least one high-profile ’70s porno. But there’s far more to it, with cop-show chase-scene jams (“The Fuzz”) sharing wax with some genuinely bizarre prog-funk (“Ill Wind” Pts. 1 & 2 and “Quantum” are keepers).
