In case you're wondering why I'm suddenly obessed with them, I saw them live last night and they were great! Anyway, these are a bunch of really good new-ish artists you should check out...
12twelve (Jazz/House fusion type thing with some Post-Rockish influences)
Aerial (Dutch Post-Rock band)
The Changes (Chicago-based Indie Rock band)
Hot Chip (Mellow-ish Electronic)
Hypatia Lake (Noisy Shoegaze-ish Post-Rock)
I Love You But I've Chosen Darkness (Indie Rock, their EP was produced by Britt from Spoon!

)
The Most Serene Republic (Indie Rock band from Canadia. They're on Arts & Crafts, so they have to be good!)
Portugal. The Man (typical Indie Rock stuff)
Rahim (Artsy Post-Punk influenced Indie Rock)
Red Sparowes (Best Post-Rock album of last year, hands down)
Rumble In Rhodos (More Indie Rock stuff, I don't really like their album all that much, but a friend of mine swears by it)
Someone Still Loves You Boris Yeltsin (Really good Indie Pop)
And as always whenever someone asks me to recommend them something, listen to lots and lots of Les Savy Fav.
