As we fast approach April 16 - this year's Record Store Day, the music geek's Christmas - we're starting to see more vinyl reissues happening in independent stores especially for the occasion. Two of the most recent ones take us back to the rock and roll sound of the 1990s, from traditional grunge to spacier, experimental styles.

Twenty years ago, Matthew "Slim" Moon formed a record label in Olympia, Washington, with the intention of putting out eclectic records, from spoken word to punk. That label, Kill Rock Stars, is still going strong to this day, having attracted indie artists from Sleater-Kinney to The Decemberists. And for Record Store Day, the band is reissuing its first major release, a compilation also called Kill Rock Stars. Featuring tracks by Nirvana, Bikini Kill and The Melvins, this set will be limited to 2,000 vinyl copies in silkscreened, hand-numbered sleeves.

Not long after the grunge explosion, another interesting rock movement began: the rise of The Flaming Lips. The Oklahoma-based band, known for its densely-arranged, occasionally catchy tunes and theatrical live shows, continues to stay strong - this year, they're documenting their entire creative process, during which they will release a handful of songs each month - and longtime label Warner Bros. is set to honor their legacy for Record Store Day as well. Heady Nuggs: The First Five Warner Bros. Records 1992-2002 collects the band's first five major-label releases (Hit to Death in the Future Head (1992), Transmissions from the Satellite Heart (1993), Clouds Taste Metallic (1995), The Soft Bulletin (1999) and Yoshimi Battles the Pink Robots (2002)) on 140-gram vinyl. (The band's official Web store will also offer, in limited quantities, a version of the set on five different colors of vinyl.)

Have a look at the track lists after the jump.
