My favorite holiday, Record Store Day, falls on Saturday, April 21&#151just one month from today. Independent record stores across the nation will celebrate with contests, giveaways, all kinds of limited-edition releases, in-store performances by exciting bands, and lots of other fun stuff. Check the Record Store Day website for details and participating stores near you.
