King Crimson is guitarist/composer Robert Fripp’s monarchy. Formed in the late 60s, the band’s first LP In The Court Of The Crimson King featured Greg Lake (EL&P) and is widely considered the first true ‘prog’ album. The word progressive is totally appropriate. After three excellent and varied albums, Fripp split the band, a move he orchestrated several times over the decades. The various incarnations—Fripp has gnomically observed that “King Crimson exists when there is King Crimson music to be made”—have differing musical profiles and characteristics, but all feature powerful, intricate music with Fripp’s guitar darting in and out of the centre. The first three LPs are classics, as are Larks’ Tongues In Aspic and Red. From the 80s, Discipline is a highlight, while the later sound of the band is well illustrated on Live in Vienna (2018). Fans will want the entire catalogue, of course, which is where the boxed sets shine.
