Patti Smith is undeniably cool. In 1980, she straddled the dead space that followed the end of rock and roll (as it was known to that point) but preceded the stranglehold of punk with her seminal album Horses. Nirvana is undeniably cool. After the release of their album Nevermind in 1991, the year that would be 1992 had no hope of swimming with the current and, instead, swam upstream into Grunge. When both artists sing the same song you get two sides of a very hip coin. To piggy-back on last week’s Courtney Love adventure, this week’s Throwback Thursday gives you the oft-imitated video for Nevermind‘s first single, “Smells Like Teen Spirit,” in comparison with a Patti Smith video of her “Smells Like Teen Spirit” cover.
