The Thermals have been around for quite a while.  Since 2002.  And they've had quite a close association with Death Cab for Cutie, with Chris Walla producing a number of their albums.  I picked up their 2009 album Now We Can See and their 2010 album Personal Life.  Both are pretty solid power pop albums.
"I Don't Believe You".  Love that Sleater-Kinney/Wild Flag cameo.
"Not Like Any Other Feeling"
"Never Listen to Me"
and "Now We Can See".
