Prog Related bands

Queen

Not all of the bands that have been a part of the history and development of progressive rock are necessarily progressive rock bands themselves. This is why a genre called Prog Related is included, so that all the bands that complete the history of progressive rock are included, whether or not they were considered full-fledged progressive rock bands themselves. There are many criteria that are considered when deciding which bands are prog related. Very few bands will meet all of this criteria, but this list will give an idea as to some of the things that help evaluate whether an artists is prog related or not: 

1. Influence on prog rock 
The groundbreaking work of artists like Led Zeppelin and David Bowie affected many genres of rock, including at times progressive rock. Although both of these artists created rock music in a dizzying array of genres, both contributed to the ongoing history of progressive rock several times within the span of their careers.

Led Zeppelin-Black Dog (Led Zeppelin IV, 1971 UK) 


2. Integral part of the prog rock scene 
Although Led Zeppelin, Wishbone Ash and Black Sabbath may seem like mere hard rock bands, in their time they stood apart from other hard rockers with their more serious lyrical content and more developed compositions. Put simply, in the early 70s every prog rock record collector usually had full collections of all three of these artists. These three bands were very much part of the prog rock scene without being total prog rock bands themselves.

Wishbone Ash-The King Will Come (Argus, 1972 UK)


Black Sabbath-War Pigs (Paranoid, 1970 UK)


3. Influenced by prog rock 
From the late 60s till about 1976 the progressive tendency was in full effect in almost all genres of music. Once again, as we enter the second decade of the 21st century a melting pot of prog metal, math rock, progressive electronics and post rock influences have made a progressive tendency in rock music almost more a norm than a difference. Yet in other periods of musical history receiving influence from progressive rock could really set a band apart. It is almost a given that most of the artists listed in the prog related category were influenced by the development of progressive rock, such as Led Zeppelin, David Bowie and Queen.

Queen-Bohemian Rhapsody (A Night at the Opera, 1975 UK)


Led Zeppelin-Kashmir (Physical Graffiti, 1975 UK)


Rainbow-Tarot Woman (Rising, 1976 Multi-National)


4. Location 
Progressive rock did not develop at the same time all over the world. As late as the mid-70s, for example, the US had very few original progressive rock bands that did not sound like exact copies of British bands. Journey was one of the first US bands to present a uniquely American brand of prog rock before they eventually became a mainstream rock band. There are bands that helped the progressive rock scene develop in their corner of the globe, even if those bands were like Journey and were known more for being mainstream rock bands. 

Journey-Topaz (Journey, 1975 USA)


5. Members of important prog rock bands 
Although most of the recorded solo output of artists like Greg Lake of ELP and David Gilmour of Pink Floyd falls more in a mainstream rock style, their contributions to progressive rock in their respective bands insures them a place in the prog related sub-genre. The same goes for the supergroup Asia composed of former members of important prog rock bands.
