Grizzly Bear seem to come from another time period, but exactly which period that is can be hard to nail down. They're influenced by just about every time period, and it's amazing how well they're able to put all of those influences together to create something great. This song, which features Victoria Legrand (of yesterday's 'Song of the Day' band Beach House) in the chorus, is the pinnacle of those influences. With a piano sound straight out of the early 1900s, harmonizing out of the 60s, and a song structure that could only be modern, "Two Weeks" is one of the more beautiful songs I've ever heard. Only a few full-length albums into their career, this band just keeps getting better and better, and it's amazing to think of the music they might be making in a few years.
