[5][6][7][8][9][10][11] From 1978 to 1988 he competed as a pianist in about a dozen international classical piano competitions (Senigallia, Stresa, Bardolino, Torre Pellice, Capri), receiving two first prizes.

[26] In June 1996, Docker briefly returned to classical music with a recital called "Paesaggi Esotici", performed at the Turin Museum of Natural History.

Featuring Mio Nakamura on vocals, the program included operatic arias and traditional songs linked by the common theme of "the exotic" (particularly Asia).

[27] In November 1999, he performed Allegro de Concierto by Enrique Granados at the SFI-Västertorp in Stockholm for its yearly Kulturdagen (Culture Day).

Its album The Mystic Technocracy – Season 1: The Age of Ignorance was released in 2012 on Lion Music, described by the artist's record label as a progressive rock space opera.

[32] In 2016 Docker released a crowdfunded sequel entitled The Heisenberg Diaries – Book A: Sounds of Future Past.

Despite this, he has confirmed that Anna Portalupi (Hardline) will be playing bass on the album and that drumming duties will be handled by Elisa "Helly" Montin (The Anunnaki, Cattivator Of Death, Übermensch).

However, Docker later cancelled the entire festival, for several reasons including inter alia "the chronic absence of public at the evenings despite the constant online and printed promotion".
