Loosely talking, there are two sorts of Jeffrey Silverstein tune: freewheeling instrumental jams and cosmic folks ballads. “Sunny Jean” lands squarely within the latter camp. The ode to his spouse is awestruck and psychedelic. Silverstein’s gruff, spoken vocals relaxation atop an ethereal instrumental, which is carried by an earthy rock groove peppered with acoustic and slide guitar thrives. “And in case your blues slip away / You are in your pure state / A quiet confidence / A way of permanence,” Silverstein placidly intones on the lower’s refrain. All of it comes collectively to evoke a reflective drive down an expansive desert freeway ad infinitum. If the Grateful Lifeless existed in an alternate universe the place it operated adjoining to the 2010s Brooklyn surf-rock increase, that band would most likely sound one thing like this.
