Spring is finally coming around, (it's just late here in Casper) and that brings us the 7th annual Record Store Day. This unofficial holiday is celebrated by select retailers throughout the U.S., Canada, the United Kingdom and a few other countries.

This year's Record Store Day is proving to be one of the most expansive yet, with more than 400 special releases headed for U.S. stores alone.  Obviously, there are way too many discs to list, but among some of the noteworthy acts represented are Aerosmith, The Allman Brothers Band, The Animals, David Bowie, Eric Carmen, Sam Cooke, Creedence Clearwater Revival, The Doors, The Everly Brothers, The Grateful Dead, The Jimi Hendrix Experience, Otis Redding, Ronnie Spector with The E Street Band, Bruce Springsteen, The Yardbirds and The Zombies.

Here's some specific information about a few of the releases sure to interest audiophiles:

- David Bowie's "1984" picture disc -- a seven-inch single featuring a photo of Bowie with famed beat author William S. Burroughs, and including the original version of the song and a live rendition from a December 1974 TV appearance.

- Creedence Clearwater Revival's The 1969 Singles -- a 10-inch white-vinyl disc featuring four singles, a-sides and b-sides, that the band released in 1969.
