There's writing on the wall that speaks of time immemorial, where symbols exist on the edge of language and abstraction.  It's upon this precipice that Dominic James Marshall makes his mark, at the helm and on the keys of Cave Art - a slate of scintillating digital sounds, spontaneously arranged, etched in wax. The project is a thoughtful and inventive response to a long tradition of musical sampling.   Familiarity is a vessel through which Marshall channels a fierce artistry and selection is at the heart of what moves it. The trio build upon what makes beat music burrow into us so deeply, maxing out their offerings of giant synths, splintering chords and impactful beats to soul-shifting degrees.   Marshall plunges into the uncanny valley and frolics in it, inventing a fresh path for the genre with irreverent wit and divine grace.
