Sjaak Herbert makes his return on 90watts after last years' Serenity single and his remix for Pascale's NAN. But this time the talented Dutchman is not alone! Here on 'Mass EP' he teams up with Ashwin van Dolder for what is the debut release of their new joined effort project named PolarNL.

They're kicking things off with the deep but moving tech house vibes of 'Hubble'. The track starts out quite moody but slowly but surely builds up until the duo open up the roaring synths and add some proper jackin' percussion to make your booty wiggle.

'Brain Damage' is, what the title might suggest, one for the head. A deep and hypnotic groove completed with a story about, well.., the brain obviously. Proper late night house music vibes here with a hint to the early days of electronic music.

Finally the guys show us 'Rocket To The Moon', house music in it's purest form. Jacking beats, cleverly placed synth shots, a wobbly bassline and a relentless infectious groove. Nothing short of spectacular this one.

Three tracks packed with timeless underground (ware)house grooves here, by a new duo with a bright future ahead of them!
