AERO 21 presents 'Polar Lights', his first vocal production, a collaboration with the singer Svenja. The original mix builds smoothly up but still effective with strong drum hits and basslines as well as Svenja's vocal chops which add a new colour to the track with a trancy lead melody. DYNAMICA Mix is another version of AERO 21 which has a driving bass drop after the breakdown and suitable more for the clubs. Etasonic shows his talent again with his great remix. It builds up with high speed and power. After shifting to low gear for some emotional moments in the break speeds up again with full throttle. Another uplifting star UDM delivers the 2nd bomb as we expect from him. With powerful drums, rolling basslines and edgy leads it has everything to lift you up in full euphoria.
