Twenty-ten turned out to be a killer year for indie fans. Arcade Fire knocked Eminem off his Billboard throne; established acts like The National, The Black Keys, Spoon, Sufjan Stevens and LCD Soundsystem continued their reign, headlining festivals, showing up all over TV shows and advertisements, and piling up more fans than ever. Then there were new projects from Jonsi (of Sigur Ros) and Danger Mouse and James Mercer (of The Shins) and newcomers like Mumford & Sons, Surfer Blood and Twin Shadow keeping all those vets on their toes. Here we've compiled 20 of the best alternative and indie albums from 2010. You can listen to all of them right here on Rhapsody.
