Singer-songwriter Matisyahu has been on a journey inward for more than a decade. The journey has been private and public. The journey has at times been explicitly external, even while being driven by internal change. Now, nearly thirteen years after the release of his first studio record, Matisyahu and his band have done something unmatched in his past repertoire; they have crafted that journey into a musically thematic eight-song-movement.

The band features longtime guitarist Aaron Dugan, Dub Trios bassist and drummer Stu Brooks and Joe Tomino, and keyboard virtuoso BigYuki — and the journey starts with them. The band improvised for hours in the studio with Matisyahu watching on as an admirer without singing a single lyric. Out of the improvisations grew melodic themes, rhythmic peaks and valleys, blissful and proto-song guitar passages, deep dub meditations and ultimately an inspired instrumental record unto itself. Only once the band had crafted this musical narrative, did Matisyahu begin to work on a lyrical narrative of his own — a lyrical narrative that is simultaneously informed and integrated with the music yet driven by Matisyahus own personal journey. The result is Undercurrent, Matisyahus sixth studio album.

The record is musically Matisyahus most courageous release to date and lyrically his most vulnerable.
