Prog rock has undergone such a renaissance in the past three years it now forms a major and respected part of rock music as a whole, its influence ranging from as far as the original practitioners like Pink Floyd, King Crimson, Yes, Genesis and co through '80s standard bearers like Marillion and Asia through to the progressive movers and shakers of today; bands such as Porcupine Tree and Dream Theater, Muse and Radiohead, The Mars Volta and Coheed and Cambria.
