Soundgarden - Badmotorfinger LP

Soundgarden's songwriting takes a quantum leap in focus and
consistency on their epic 1991 set, turning in a lean, muscular
album that signaled their arrival in rock's big leagues. A surprisingly
cerebral listen too- it's all twisted and gnarled, chock-full of dissonant
riffing, impossible time signatures, howling textural solos, and weird,
droning tonalities.
