Here’s a deep cut for the prog faithful. A 1985 BBC TV South documentary on Robert Fripp, billed “The King of Crimson,” has resurfaced online, gathering rare footage, interviews and concert clips of the King Crimson mastermind in one place. It’s Fripp as you’ve rarely seen him, the guitarist and bandleader whose restless approach reshaped progressive rock from ‘In The Court Of The Crimson King’ onward. The soundtrack reads like a tour through his catalogue, running from “21st Century Schizoid Man,” “Epitaph” and “The Court Of The Crimson King” through “Larks’ Tongues In Aspic (Part II),” “Three Of A Perfect Pair” and his Andy Summers collaboration “Hardy Country.” For longtime followers it’s a treasure, and for newcomers it’s a fascinating window into one of rock’s most singular minds.
