It’s been one of the most hotly anticipated albums of 2009 since it was first announced: “Dark Night of the Soul,” a collaboration between the producer Danger Mouse (Gnarls Barkley, Gorillaz, The Black Keys) and critically acclaimed psych-rock act Sparklehorse (a.k.a. Mark Linkous). Due to unspecified legal issues with EMI, though, the project’s official release has been either scrapped altogether or put on indefinite hiatus.
From the statement given by Danger Mouse, it sounds as though the former is the case. A representative said, "Danger Mouse remains hugely proud of ‘Dark Night Of The Soul’ and hopes that people lucky enough to hear the music, by whatever means, are as excited by it as he is."
