The Ex had long collabroated with ICP members. Instant marked the band’s first album of entirely instrumental and improvised music. Instant’s 32 tracks feature shifting duos and trios of musicians performing on a wide array of conventional (electric guitars, reeds, brass, etc.) and non-conventional (e.g., toffee-tin bass) instruments. Though the entire album could have fit onto one 70-minute CD, the band formatted it for a briefer listening experience with each of Instant’s 35-minute discs containing 16 short tracks.
