One of my favorite recent albums is very hard to explain in any recommendation. Battles, a nerd-rock or math-rock supergroup is unlike anything else you have heard (unless you really dig math rock). I think Mirrors was released last week, but I have been listening a few weeks (came out in Europe before that) and feel ready to recommend them.
I can only describe it as avant garde jazz mixed with Kid A era Radiohead by an IT department that really like childish vocal stylings. In fact, my 4 year old son likes their lead single, Atlas, as much as I do (but for profoundly different reasons).
Surprisingly, the arbiters of cool at Pitchfork and I agree for once. Read their review (but leave the site immediately, unless you are able to think for yourself and ignore their wrongheadedness on most albums).
Watch the wonderful Atlas video here.
