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".
