A second wave of progressive rock bands appeared in the early 1980s and have since been categorised as a separate "neo-progressive rock" subgenre. These largely keyboard-based bands played extended compositions with complex musical and lyrical structures. Several of these bands were signed by major record labels, including Marillion, IQ, Pendragon and Pallas. Most of the genre's major acts released debut albums between 1983 and 1985 and shared the same manager, Keith Goodwin, a publicist who had been instrumental in promoting progressive rock during the 1970s. The previous decade's bands had the advantage of appearing during a prominent countercultural movement that provided them with a large potential audience, but the neo-progressive bands were limited to a relatively niche demographic and found it difficult to attract a following. Only Marillion and Saga experienced international success.
