Jacks played depressi-psych years before it was cool. Vacant World is their first album. The songs are all folky and poppy with depressive/psych undercurrents there to keep the listener on edge and feeling bad over the course of the album. It never gives the listener a reason to be on edge because it doesn't explode at any point, and its psychedelia is more of an outcome in the listener than an explicit stylistic decision. Although its undercurrents remain undercurrents, Vacant World will depress you and it will make you dizzy, entirely because of these undercurrents. Undercurrents.
