Love it or loathe it, there is no denying the lasting impact of Prog Rock! We examine it's rise, and sample various sub-genres. Discoveries include the "Rosetta Stone" of prog, and the dirty secret of the "Canterbury Scene". Dig the hypnotic grooves of Can, the ironic satire of Jethro Tull, and life on planet Kobaïa. All hail the amazing Greg Lake.
