KURT COBAIN WAS NOT a generation’s representative, a spokesperson, or even a rock star. Many tried to press him into these and other molds, much to his frustration, but it happens that he was a songwriter always on the search for a new sound. When he died, by medical estimation on the fifth of April in 1994, some (among them R.E.M.’s Michael Stipe) believed he was about to abandon the grunge formula for which he had become known. There is evidence he was about to quit music altogether. In any case, the posthumous album, MTV Unplugged in New York, is the best indication we have of the band’s unrealized prospects. Perhaps Nirvana’s most accessible and widely known recording, Unplugged is an accomplished example of musical understatement, disclosing Cobain’s intuitive ability to compose songs (or in the case of The Vaselines, Meat Puppets, Lead Belly, and David Bowie covers, select them) which complement his particular vocal and playing styles.
