SL THEORY release their first official video and single for the song “You Never Happened”. The track is taken from the band’s upcoming album “Cipher” out on December 6th, 2019 and can be viewed here:

Shot at Soundflakes Studios in Ellinikon. Directed & edited by Manos Georgakopoulos.

Get “Cipher” now:

Available on Tri-fold  Digipack CD & Digital streaming/download format.

This is an album where the band displays in a unique, well-thought and precision-executed way all the elements that it is building their name on: sophisticated compositions and quality musicianship on the path of Prog Rock and AOR giants like Kansas, Styx, Queen and Foreigner. From epic Prog Rock, to Heavy AOR and even a couple of surprising bluesy and funky touches, the whole musical heritage of SL THEORY is present in “CIPHER”. Composition, lyrics, harmonies and performance made just the way it used to be made. With great respect to the fans of heavy sound. No tricks, whistles and bells.

“Cipher” will be released through ROAR! Rock of Angels Records, physically and digitally worldwide on December 6th, 2019.
