Hard rock

"Hard rock or heavy rock is a loosely defined subgenre of rock music typified by a heavy use of aggressive vocals, distorted electric guitars, bass guitar, and drums, sometimes accompanied with keyboards. It began in the mid-1960s with the garage, psychedelic and blues rock movements. Hard rock developed into a major form of popular music in the 1970s, with bands such as the Who, Boston, Led Zeppelin, Deep Purple, Aerosmith, Kiss, Queen, AC/DC and Van Halen. During the 1980s, some hard rock bands moved away from their hard rock roots and more towards pop rock. Established bands made a comeback in the mid-1980s and hard rock reached a commercial peak in the 1980s, with glam metal bands such as Bon Jovi and Def Leppard and the rawer sounds of Guns N´ Roses which followed up with great success in the later part of that decade." - (en.wikipedia.org 27.12.2020)
