Following up on their last Enhanced Progressive EP 'Cloverfield' & 'Bakcheia', are Argentinean duo 19 Hz returning with the latest sounds to ooze from the studio. Injecting unique style into 'The Key', the duo pioneer soft plucks and emotional melodies throughout. Starting with a heavy club bass in groovy progressive strides, this track focuses on immaculate harmonies during the breakdown before the epic lead riff bursts into life. A solid arrangement that hits all the right notes yet again, with early support from Above & Beyond!
