A third wave of progressive rock bands, who can also be described as a second generation of neo-prog bands,{{sfn|Hegarty|Halliwell|2011|p=199}} emerged in the 1990s. The use of the term "progressive" to describe groups that follow in the style of bands from ten to twenty years earlier is somewhat controversial, as it has been seen as a contradiction of the spirit of experimentation and progress.{{sfn|Gill|1995|}}{{sfn|Hegarty|Halliwell|2011|p=19}} These new bands were aided in part by the availability of personal computer-based [[Digital audio workstation|recording studios]], which reduced album production expenses, and the [[Internet]], which made it easier for bands outside of the mainstream to reach widespread audiences.{{sfn|Karnick|2003|}} Record stores specialising in progressive rock appeared in large cities.{{sfn|Gill|1995|}}

The [[Shred guitar|shred]] music of the 1980s was a major influence on the progressive rock groups of the 1990s.{{sfn|Gill|1995|}} Some of the newer bands, such as [[the Flower Kings]], [[Spock's Beard]] and [[Glass Hammer]], played a 1970s-style symphonic prog, but with an updated sound.{{sfn|Lucky|2000|p=47,127}} A number of them began to explore the limits of the CD in the way that earlier groups had stretched the limits of the vinyl LP.{{sfn|Hegarty|Halliwell|2011|p=200}}
