Singer-songwriter Conor Oberst s debut album for Nonesuch Records, Upside Down Mountain, is, as its title implies, a study in contrasts, a glance up to the heavens and a glimpse into the abyss. "There s a certain solitude to this record," Oberst admits, and themes of loneliness, dislocation, and regret repeatedly surface. Yet its making was far from solitary, as Oberst gathered friends old and new for the recording, including producer Jonathan Wilson, engineer Andy LeMaster, bassist Macey Taylor, multi-instrumentalist Blake Mills, and the Swedish sibling folk-rock vocal duo First Aid Kit.
