A: Progressive (Prog) Rock
1968-1982 –
This sub-genre was influenced by psychedelic rock, classic rock, hard rock and also jazz and fusion (the mix of rock & jazz). With the release of Sgt. Peppers, many loose concepts to full-on conceptual albums like the Small Faces 1968 “Ogden’s Nut Gone Flake” or The Who’s “Tommy” were released during the psychedelic phase and a newer subgenre emerged as “prog rock” or progressive rock.
Staring with Beatles, the Beach Boys, the Byrds, and The Who released programmatic albums throughout the psychedelic era .Newer bands like Pink Floyd, the Nice, the Grateful Dead gave way to even newer bands like Yes, King Crimson, Emerson Lake & Palmer, and Jethro Tull who were stretching the boundaries of rock music even further and perfected the “programmatic” album sophistication and art, starting in the psychedelic era.
