I need more pretentious indie and more low-key folkish stuff please.

the trials of van occupanther by midlake is a great mellow rock album.

From the bands not already mentioned:

Johan (OMG they're awesome!!)
The Raconteurs

Also your list lacks some Wolfmother!!!

[CrazyIrishman]

The John Butler Trio check out the album Sunrise over Sea
He's an Australian dude with some aboriginal music influences. Song autoplays on his homepage.
Air-LateNightTaleswhich is a 2006 remix album, most of the songs are light jazz/folk type music. (not electronic at all really)

[mike l.]

Tom Waits, all of his stuff- so varied but so great

[claudenm]

Rasputina is one of the worst bands I've ever seen/heard.

Neil Young's Prarie Wind, Harvest Moon, On the Beach or Everybody Knows This is Nowhere are all great albums.

[MarkSummers]

Destroyer, specifically you might like the song "your blood"

[Potvaliant]

Cowboy Junkies
John Prine ("The Missing Years" especially, though it's all good)
Dan Bern
Ron Sexsmith
The Mendoza Line
Richard Thompson

[neuroman]

The Russian Futurists

I randomly stumbled across their music and (I think) it's right up your alley, tom.
