"The 1970s: It was the decade that punk and disco landed like a bludgeon against the bourgeoise stronghold on the arts as virtuosity made way for music of attitude and individualism. It was the decades that saw David Bowie unleash a constant swirl of singular masterpieces and inspire millions with his creative character studies. It saw Joni Mitchell make everybody cry with the folk explosion’s last hurrah on Blue, Californian rock ‘n’ roll went out in style with LA Woman, and the emergence of new masters on albums like London’s Calling, Marquee Moon, Paranoid, Horses, Rumours and an endless string of others. In short, it was the great decade of art in history."
