Progressive rock expanded the scale of rock songs through longer, multi-section compositions, extended instrumental passages and ideas drawn from classical music, jazz and experimental composition. The British psychedelic scene of the late 1960s fed directly into the form, with King Crimson’s 1969 debut becoming an early landmark before Yes and Genesis carried prog into the 1970s.
Recent coverage reaches further from classic prog. Slug Comparison brings a compact six-song release into the archive, Kraanerg connect zeuhl, experimental metal and classical composition, and Corima approach the field through another zeuhl route. Neverbody carry progressive ideas into post-rock. Zeta connect post-rock, experimental music and post-hardcore.
