2011’s Hurry Up, We’re Dreaming was a gargantuan album to add to the canon of gargantuan M83 albums. Junk is rather different, but no less thrilling. Out go the blown-out anthems and in their place, nostalgically candied pop, disco and soul gems. It bobs merrily between gloriously indulgent (“Do It, Try It”, “Go!”), gloriously silly (“Moon Crystal” sounds like a ‘70s TV theme), and deeply romantic (“For the Kids”, “Atlantique Sud” and "Sunday Night 1987”). “Solitude”, meanwhile, is gorgeous, cinematic and blessed with a spellbinding keytar solo. It’s that sort of album.
