Vangelis' Let It Happen is a blissful, dreamy proto-Balearic song from his third album, Earth, (1973) with a bass-line that wouldn't be entirely out of place in an Air France song. Vocals were provided by F.R. David, who would score big with the pleasantly pleading Euro-synthpop song Words, also available above.
Beatfanatic's remix turns it more into a Still Going-style sitch: layering it with four-on-the-floor disco beats and letting the bassline carry you through an 8 minute expansion from the original. Don't hold his poorly chosen moniker against this Swedish boy ("I am your BEAT MASTER!" "I'm gonna cook up some funk in my groove kitchen!" "Take a trip through my rhythm garden!").
For his Late Night Tales mix (released in July 2007), Lindstrom tweaked Let It Happen into a darker and more sinister affair, the expansive original is now a constricted straight-jacket of a song that pops and stutters with a hammering bass-thump instead of our beloved bassline and decaying acid arpeggios... The vocals are provided by long-time collaborator Christabelle Solale If the Vangelis original calls to mind Meditarranean islands, Lindstrom's version is the musical equivalent of driving your 1980 Ferrari 308 GTSI in the abandoned city centre of Tokyo at night, during a rainstorm.
Grab Demis Roussous' version from the always amazing American Athlete blog. The gargantuan Grecian chanteur began his career in the psych-group Aphrodite's Child along with Vangelis and went on to greater, schmaltzier fame as a solo performer and, memorably, a birthday boy terrorist hostage to Lebanese hijackers in 1985. Mr. Roussos has a new album out in February of next year, two songs of which you can preview on his Myspace page.
