I really enjoyed their first two major full length albums. The ones that followed seemed to be okay but not as good as their first two. However, they woke me up with their last release with Good Monsters which I believe is in competition to be their second best album that has been released thus far.
On April 21st, 2009 they will be releasing a brand new album called "The Long Fall Back to Earth". I listened to some clips of the songs that will be on this album and I must say I am impressed. I will have to listen to it a few times after it comes out but it looks like they are still progressing in their later years.
Thanks Jars for making such wonderful music!
