In 1999 Cass & Slide originally released 'Perception' which quickly became an undisputed Trance classic of the era, rising to prominence on Sasha's iconic Global Undergound Ibiza, Tiësto's renowned 'In Search of Sunrise 2' and Pete Tong's Essential Mix on BBC Radio 1. PRAANA now revive the track with a melodic makeover, whilst paying homage to the original and receiving props from Cass & Slide along the way.
