Record Store Day is right around the corner (this Saturday April 21, but you already knew that), so here's a few updates and miscellaneous pieces of information that will help you manage your weekend and make it as enjoyable as possible.

Record Store Day Unveils Extensive List of Releases, fun. To Play Boston In-Store

First off, if you haven't downloaded it yet, The Vinyl District has developed a free app for both iPhone and Android that allows users to locate the nearest independent record shop via its GPS locator. While useful in unfamiliar cities and neighborhoods throughout the year, the app is that much more useful this weekend, especially its social features. Users can make their own Vinyl District accounts or sign in with Twitter or Facebook and check in to record stores, comment in the "shout" section, and share what gems they've uncovered with others around them. There's also an events section that highlights record fairs, though it leaves out RSD-specific events.

Buck Owens, M83 Among Record Store Day Releases

Record Store Day has also put out its own app for iPhone and Android phones, called RSD Guide, though users - at least in the iTunes App Store - have reported it to be slow and somewhat glitchy. The RSD Guide has the full list of official releases, includes video premieres and contests, and is also GPS-enabled to find the nearest RSD-participating shop to your location.

To help commemorate the big kickoff on Saturday, the RSD website has a huge list of bands doing in-store performances as well, mostly complete with set times and signing information. We've listed a few of the names and the stores they'll be stopping by below, but check out the full list here.

Easy Street - Queen Anne - Seattle, WA
Dierks Bentley, 1 PM - purchasing his new CD Home delivers the buyer a wristband good for VIP entry and a signed poster
Brad, 4 PM - purchase the band's new album United We Stand before the street date, and stick around for a signing after

Disc Go Round - Corpus Christi, TX
Mastodon, Opeth, 2 PM - members of both bands will be signing autographs

Sound Garden - Baltimore, MD
