Time for a rare musical recommendation: the Aluminum Group. They cite the Carpenters, Sergio Mendes, and Brasil 66 as musical influences, and their "lushly orchestrated pop" is simply divine. They've been around since the mid-1990s, but I only just heard them. Where HAVE I been?!
Anyway, here are some favorites:
Lovely Day will make you happy.
The song "Post It", about a lost post-it note, will make you want to rummage in your purse. Hear it and other songs from their 2008 release Little Happyness at MintyFresh, their "record" label (sound quality isn't great, but you get the idea). You can also read a review of Little Happyness at Pitchfork Media.
