Andrew Jackson Jihad/Ghost Mice split. Good ol' folk punk. I'm slowly beginning to fall in love with AJJ. Their craziness, hilarious lyrics, and intensity all mixes together into a terribly fun package.
Russian Circles,
Station. More post-metal from these guys, more awesomeness. This lies a bit more on the "post" side than the "metal" side and features a lot of ambient-influenced tracks. The most relaxing metal I've heard to date.
Side Brain,
On The Second Moon Of Earth. This is... weird. Basically, it sounds like Flying Lotus doing a dubstep album that utilizes a lot of old video game sound effects and what I presume to be samples. My little brother, a huge vintage video game geek, introduced me to his music on Youtube. It's very, very good. Here's a video of him playing a song (not on the album)... on a Sega Dreamcast.
