Earlier in 2012 Mannion made his first appearance on German label Permanent Vacation with the Mountains EP. He'll stick with the imprint for his debut album, Changing Days. The LP sees him largely abandoning conventional house tempos and structures in favour of a more song-based approach that prominently features his own vocals. Mannion claims that his aim with the record was to "[have] an emotional resonance without being overly sentimental or schmaltzy... add something to [listeners'] lives that's more than a hands in the air 5 AM moment in a club." All ten tracks on Changing Days are previously unreleased.
