I would have gone for Arriba Records but it's typically hard house - Baby Doc stuff. Maybe lately they are into melodic stuff. Come to think of Arriba Sound System - I Got Chucked Out has some melodic moments.

Anyway, Arriba Records are mainly yellow, red down the bottom, a red circle in the middle with a yellow arrow pointing north.

btw, who was the DJ and where?

Just had a look at their website, na I dont think thats it. It was kind of like a simple yellow arrow like you see on traffic lights on a white circle.

It might have been euphoric house at a stretch, but it was still pretty driving stuff. Almost as melodic as something like airbase.

It was one of the regular DJs at Habit. Lee Hardy or James Metcalfe I think...
