For those who came of age in the 1990s it may be hard to believe, but Nirvana’s “Nevermind” album turns twenty years old this week. Considered groundbreaking by some and over-hyped by others, the album is still often played and discussed two decades later. Two music writers share their opinions of this seminal album. Ben Ratliff is a music critic for our partner, The New York Times, reassessed “Nevermind” in last week’s NYT POPcast. Steve Kandell editor-in-chief at Spin Magazine, saw Nirvana play in the 90s, interviewed Dave Grohl, and put together last month’s Nirvana tribute edition of Spin.
