The word Simultaneity is a technical term from the theory of Special Relativity representing two distinct events happening at the same time. This fluidity is embodied in the musical exploration of Ari Tsugi. Comprised of mostly self-taught musicians, the soundscape is a unique melting pot of UK Jazz scenes and the raw energy that comes from psychedelic rock. Produced and mixed by Glasgow-based musician Sam Bancroft (Starsky-Rae) alongside engineer-producer Villus Vilo Jokubaitis, the album features offerings from Liam Shorthall and India Blue (Azamiah) alongside the original Ari Tsugi trio -Clement Gaud, Joe Weisberg and Mashu Harada - with keys from Angus MacDonald being added later down the line.
