Retrospective is a progressive rock band formed in 2005, in Leszno, Poland. It started off with Robert Kusik (drums) and Maciej Klimek (guitars). Although two wasn't enough, they started their search for members to their band. Shortly after, Alan Szczepaniak (guitars), a friend from the Klimek's neighbourhood, was introduced to the band on one of the practice sessions. His skills and passion to unconventional playing earned him a way in.
