Not many rock stars have had the lasting impact Nirvana frontman Kurt Cobain has. Twenty-five years ago the world lost the grunge icon to suicide. However, the singer left behind a legacy of work that music fans of all ages continue to explore, appreciate, and learn from.

In the seven short years of Nirvana’s career, the band sold more than 80 million albums demonstrating how much their music resonated with an entire generation. Whether or not Cobain accepted his star-status, the 1991 album Nevermind shot the band to worldwide fame. With each album that followed, Cobain stayed true to his punk ideals and amazed audiences with his edgy, controversial performances.

Much of Cobain’s greatness is displayed through Nirvana’s MTV Unplugged performance back in 1994. Not only did the band perform their own “About a Girl,” they also decided to take a spin at a David Bowie favorite “The Man Who Sold The World,” showing their diversity in taste. Instead of playing hit after hit, they chose songs they felt were more appropriate for a stripped down set. Cobain was more invested in the musical integrity of the performance rather than boosting Nirvana’s record sales.

The raw acoustic version of “All Apologies” gave the audience a chance to hear Cobain’s throaty vocals quite clearly over his own acoustic guitar riffs, something that wasn’t as prominent in their live electric performances.

Their cover of “The Man Who Sold The World” exhibited the band’s ability to transform a piece of music into one of their own. After the episode aired, the cover became not only a fan favorite but one that was frequently played by the band until Cobain’s untimely death.

The day the music world lost Kurt Cobain was a sad one, indeed. But at least we have YouTube to let us relive his glory days on repeat.
