This one’s a no-brainer. Since Nirvana’s Nevermind turns 30 years old on Friday — and since I just posted some archival stories on Nirvana, grunge and Dave Grohl — it’s no surprise that Eric Alper and I are talking Nirvana on today’s edition of Sonic Reducers. Listen in as we discuss the new 30th anniversary edition of Nevermind, weigh in on the endless tide of deluxe edition box sets, and wonder how Kurt Cobain would deal with it all if he were alive today. Sonic Reducers. One topic. Two music nerds. Five minutes. Everything you need to know.
