I'll begin by caveating this review by saying I'm a huge fan of GusGus and have travelled to see them live.
I enjoyed their previous offering "24/7" , the first release on Kompakt. I felt that was an experimental release, stretching what could be achieved with a minimal setup of (albeit rich) synth and vocals. After the initial 3 mins of catchy pop stylings each track would depart on a dark abstract techno journey. "Arabian Horse" is by contrast a return to the form of previous releases such as "Forever", and this is in no small part due to the return of Earth to provide female vocals. The skilful interweaving of the different vocalists melodies with the pumping techno beats and bass, with almost trancelike euphoric lead synths creates a potent combination. It's the same quirky, catchy experimentation I loved in previous releases. In short, this won't disappoint existing fans, and should prove a stunning intro to those not already au fait with one of icelands better kept secrets. How they are not more popular in the uk I do not know.
