In Brief : *** Skinny Puppy, “The Process,” American.

The Canadian electronic-rock kingpins’ final album is full of intriguing vagaries. Sound collage interludes surface between gloomy lulls and stretches of driving dance grooves, both choppy and smooth. Surprisingly, there’s even a semi-unplugged track (“Candle”) featuring a distortion-free vocal drifting between gentle acoustic guitar plucking and jagged guitar work. A suitably moody swan song.
