Following on from the nostalgic synth-pop of his 2008 release Saturdays = Youth Anthony Gonzalez revives his M83 moniker from his new LA base with a concept album spilling across two discs. Morgan Kibby, who featured considerably on Saturdays lends her vocals once more, along with Zola Jesus. Other guest contributors include Brad Laner, guitarist from '90s noise-rock outfit Medicine. 　　The album has been produced by Justin Meldal-Johnsen, best known for his work with Beck, alongside playing and recording for a breadth of artists ranging from The Mars Volta to Air to Macy Gray.
