Getting back to bands that sound similar to Panda/AC... or at least a similar genre I think would be:
Yeasayer
Atlas Sound
Black Dice
Deerhunter
Dan Deacon
Those are the closest you can get, of course they don't bear the same effect upon listening that Feels or Merriweather Post Pavillion do, but they are all wonderful artists.
