Twenty years ago, SPIN magazine began with the promise to feature uncompromising writing about the music that was turning on/freaking out the Reagan generation. Through the introduction of MTV and the alternative rock revolution, it's been many things. Rude. Brilliant. Soulful. Snotty. Angry. Delirious.

In the past two decades, genres have spawned like mad, from goth, indie rock, and gangsta rap to emo and the garage rock revival. This twentieth-anniversary tribute celebrates the passion and fury of the music, with original essays, quotes, and photographs by contributors who are as hopelessly obsessed with it as you are.

SPIN: 20 Years of Alternative Music features: Alan Light on Beastie Boys, Ann Powers on U2, Charles Aaron on R.E.M., Dave Eggers on The Smiths + Morrissey, Marc Spitz on Goth, Simon Reynolds on Depeche Mode + Synth-pop, Dave Itzkoff on ’80s Teen Movies, Chuck Klosterman on Weezer, Will Hermes on Radiohead, Neil Strauss on Nine Inch Nails + Industrial, Sacha Jenkins on Public Enemy, Andy Greenwald on Emo, RJ Smith on Gangsta Rap, Jon Dolan on The White Stripes, Chris Norris on Nirvana, Doug Brod on Oasis + Britpop, Jim DeRogatis on Smashing Pumpkins, Laura Sinagra on Courtney Love, Ta-Nehisi Coates on Tupac

Music's top journalists celebrate "Spin" magazine's 20th anniversary with original essays tracing the history of alternative rock.
