100th Window is the 4th album from Massive Attack, and marked the departure of members Mushroom and Daddy G (temporarily), leaving only one founding member, 3D. 3D along with arranger/producer Neil Davidge create a brooding and dark album, with meticulous attention to detail. Here Horace Andy returns for a pair of tracks (Everywhen, Name Taken), and the group recruits Sinead O Connor to collaborate on stellar songs like A Prayer For England and What Your Soul Sings. Pressed on 180G vinyl.
