If you lost track of Sasu Ripatti's shape-shifting projects a long time ago — everything from the high-gloss house of Luomo to the twisted techno of Uusitalo — here's the deal with his longest-running alias, Vladislav Delay: much more than a clinical assortment of clicks and cuts, it's machine music with an erratic heartbeat and a serious case of the Mondays. Tummaa, or "darkness" in Finnish is a melancholic and downright massive listen, which started with loose sessions alongside clarinet/sax player Lucio Capece and pianist/film composer Craig Armstrong (a key Massive Attack collaborator who also worked with Ripatti in the Dolls). Ripatti then dropped his muscular drumbeats into the mix and went to work with his editing tools, leading to a wave pool-like listen that's impossible to pin down. Everything's out of step in Ripatti's soundscapes, from the tense title track to the bubbly, Aphex Twin-esque textures of "Mustelmia." But the overwhelming sense that things will sync up perfectly any second now keeps the record rooted in reality , making this one of Ripatti's most organic Delay efforts yet.
