Marcus Salon was the man behind the TZ series. I believe this release was before he got started with all of that. The Outlander EP is a very, very strong release.
R&S were pretty much at their peak round about the time this came out. There was not a better label on the planet.

A return to the old ways for R&S !
Both remixes bring their respective producer's personality and style into the game.
The "Frank De Wulf remix" has that elusive old-skool belgian flavour we all love him for. The next best mix next to "The Outlander vs The Alien"
The "Kevin Sounderson mix" brings 'Tronikhouse' to the party: phat, funky swing-bass that make your hips move sideways.
A Classic.

A classic example of the R&S stables' ability to re-make an excellent track and make it great.
Every person involved in this project brought their sound and personality to this project.
Standout mix: "Alien vs Outlander" -funky house bass in a metallic rave soundscape.
Top notch.

Propably the most intelligent Techno Rave Ep released in 1991 by R&S. while Beltram was pumping out tracks based on one good sound, Marcus Salon was pushing the boundaries of where Techno was meant to go.
"Vamp" is ofcourse the recogniseable track, but the rest of this Ep is better, with a smooth Industrial feel.
