Proto-metal, psych-prog, private-press: if any of these plosive descriptors lead your pleasure center to light up in anticipation, then pay attention to upstart label Machu Piccu's second reissue, an English group whose lone album was originally issued in 1972 in a run of only 50-odd copies (but could have just as easily come out via the esteemed likes of Vertigo)!
"Axeman Martin Weaver from Wicked Lady joined up with the Dark right before this was recorded, so that’s his fuzz you’re hearing, which should give you some indication of what this sounds like. A more sophisticated, proggier Wicked Lady perhaps, a Wicked Lady with more in the way of 'songs' rather than freakout jams, though this gets bluesy/jammy at times too." - Roadburn
"To be sure, other groups may have taken the formulas further or assembled a heavier, freer slab of psychedelic boogie, but concision and melody count for a lot in the lysergic world that Dark inhabited. Although Dark disbanded soon after the LP was published, cultish interest inspired a brief and well-received reunion in 1996. More than four decades after their lone LP was waxed, Dark Round the Edges deserves to be visited anew." - Tiny Mix Tapes
