Love X Stereo have announced their upcoming EP, We Love, We Leave Part 2 and opened pre-orders on Pledgemusic.com. What this does is allow fans to directly support LXS with the release.
Pledgemusic works kind of like Kickstarter and Indiegogo by allowing fans to fund artists by buying different support levels each with their own reward. $10 gets the physical release up to $5000 that gets you a trip to Seoul, Love X Stereo concert, and a guided tour by Annie.
Though the most interesting is a vinyl release of We Love, We Leave Part 2. Vinyl releases of Korean artists are hard to come by and this is a great chance to get a rare vinyl release.
At the very least, you should get support LXS with a CD purchase, but there are plenty of other options to choose from.
