Picked this up today from Simian Mobile Disco's playlist on iTunes. Had never heard this tune before but its been around since '84 (or '83 depending on what you're reading). I'm generally not a major fan of a lot of 80's electronic/electro from Europe but this has such a killer deep ass bassline that won't fail to have your dancefloor swaying.
By MegaCC on discogs:
While Europe had "Sunshine Reggae" as an A-side and "White Horse" as a B-side to what was originally a double A-side single 7" release, the US simply reversed it all. Sire Rec's and Seymour Stein had signed Laid Back up on the reputation of "Sunshine Reggae" but soon found out that "White Horse" was hitting clubs. Next up was a 12", including a remix by Shep Pettibone, that helped launch the then-nascent 12" DJ / Dance vinyl format. By now, "White Horse" rivals the James Brown track "Funky Drummer" in terms of sample uses.
I was gonna post the video but I think it takes away from how superb the tune is.
If you take a wander over to the excellent palmsout you can also find DJ Nature's Cocaine Bitch remix hanging out.
