Mmm, Ratatat. I have only heard their LP "Classics" (i think that's what it's called?). I really need to get more into them.
I picked up Radiohead's Ok Computer the other day, (i know, i know, i'm about 12 years late to the party, boo-hoo) and it's fantastic. I really didn't think it would live up to it's legacy, but my god, I've never been this glad to be mistaken.
I've also been into post rock lately; bands like Godspeed You! Black Emperor, Sigur Ros, Explosions in the Sky, and this relatively obscure japanese band called Mono. They're pretty freaking epic.
I also highly recomend the following youtube channel to people who are very into underground, good music, with lots of variety. His name is Anthony Fantano, or TheNeedleDrop, and is pretty much my idol:
*no, i did not get paid to drop this link, nor am i Anthony*

Sorry for such a large post, i'm new here, and if long posts are frowned upon, I apologize. I'm just a huge music fan
