"Larks' Tongues in Aspic" is a suite of music by the English progressive rock band King Crimson. Spanning thirty years and four albums, the series comprises five parts, all of which carry unifying musical motifs. Parts I and II were released as the introductory and final tracks on King Crimson's 1973 album of the same name, part III was featured on their 1984 album Three of a Perfect Pair, part IV (itself divided into three identically titled parts) appeared on 2000's The Construkction of Light, and the final part, "Level Five", was included on the 2003 album The Power to Believe. Despite breaking the naming convention, Robert Fripp, King Crimson founder and only constant contributor to the suite, insists that "Level Five" is part of the pentalogy.
