The album maps out a wide-open soundworld of compositional possibilities for pianist Erol Sarp and producer/electronic engineer Lukas Vogel, who have been putting their modern and unique electronic spin on prepared piano since first forming in 2012. The debut single and title track from the album ‘All The Unknown’ starts out with the clanging percussive piano figures that have danced across Grandbrothers’ previous terrain, but grows with the intensity of high-octane electronica to cast out allusions of classical romance, guided by emotive, cascading keys that collide with stuttering digital percussion.
