PROTONICA's third album "Symmetry" was recently released and features stunning collaborations with some of the world's leading Psy-Trance artists, including Liquid Soul, Ace Ventura and Captain Hook. While working on "Symmetry" they felt the urge to bring back melodic structures and elements of Trance and Goa to Psytrance - the core essentials of their past, and ingredients for the future. Piet and Ralf have worked hard for their careers and have established a strong brand with a distinctive signature sound in recent years.
