20. King Crimson, 'Larks' Tongues in Aspic' (1973)
With his third lineup in four years, King Crimson guitar maestro Robert Fripp finally tapped back into a musical energy as powerful and groundbreaking as that of his 1969 debut In the Court of the Crimson King. The group's fifth album was a masterful mélange of painstaking composition and wild experimentation, as if Fripp were depicting a madman struck with glimmers of melancholy clarity. In the end, it's difficult to tell which passages were happy accidents and which were carefully constructed; and it's even harder to determine which are more impactful, as clattering trays, chiming bells, twittering birds, understated voices and clown-toy laughter intertwine with tinny, static-filled guitar, epileptic beats and violin lines that range from gorgeous to harrowing.
