Posting Massive Attack a few days ago made me think of this, by fellow Bristollian Tricky. It is taken from the album Maxinquaye which, when I first heard it, left me completely transfixed. It was so dark and brooding, sounding like it had come from another planet. I loved the fact that something sounding so stark and otherworldly could come from somewhere that seemed so real and tangible to me.
The sample used in the song is from another Stax hero, Issac Hayes.
