(Keeley Parenteau)One big day led to years of big disappointments for Chance the Rapper . The announcement that summer of a comeback album, Star Line Gallery, only exacerbated the turbulence when it kept failing to materialize. The Big Day quickly (and unfairly) eroded much of that goodwill, and the burden mounted for Star Line Gallery to break the curse. But STAR LINE is not about globetrotting, or returning to the motherland; it’s about the lessons learned on the journey, a fitting career metaphor. Chance has always done business by committee, and one of the charms of STAR LINE is how its community-driven ethos seems to apply to its own creation.
