100 dies del rock de la dècada dels 70 i 80

The testimony of two transcendent decades for the musical memory of several generations, through 100 significant dates. Two decades that begin with the end of the Beatles, which halfway through receive a strong jolt with the murder of John Lennon, and which end with the nondescript pop of Phil Collins leading the charts while grunge is already knocking on the door . Two decades, the 70s and 80s, full of proper names, historical context and different musical movements -progressive rock, glam, punk, new wave, rap...- that redefined rock.
