Fretless guitar wizardry meets heavy Balkan grooves. Instrumental sci-fi fusion that feels like a high-speed chase through a futuristic bazaar.
Consider the Source is a definitive power trio in the modern progressive fusion scene, notable for their highly specialized 'Sci-Fi Middle Eastern Fusion' sound. Formed in 2004 in New York City, the band consists of Gabriel Marin (fretless double-neck guitar), John Ferrara (bass), and Jeff Mann (drums).
Their identity is built on a foundation of rigorous ethnomusicological study; Marin and former members traveled to India to study traditional instruments like the chaturangui and tabla, which informs their use of microtonality and Indian 'tala' rhythmic structures. Marin's use of a fretless neck allows for melodic ornamentation impossible in standard Western rock, while Ferrara’s percussive slap and tapping techniques provide a unique harmonic and rhythmic counterpoint. Critically, they are positioned at the intersection of the jam band circuit, the prog-metal underground, and the avant-jazz scene. Their influence web connects the Mahavishnu Orchestra’s high-velocity fusion to the rhythmic complexity of Tool and the world-music explorations of artists like Pachora. They are highly regarded for their live performances, which emphasize improvisational fluidity within extremely rigid, complex structures.
