After getting several responses to my Top 10 Indie Albums list, I've listened to a few good albums from 2007. I'll have to listen to them more thoroughly and write up some reviews, but all of these are worthy of my list:
Andrew Bird - Armchair Apocrypha
The National - Boxer
The Once Soundtrack
Radiohead - In Rainbows
Sigur Ros - Hvarf/Heim
I still haven't heard the latest efforts from the New Pornographers, Beirut, or Josh Ritter. Consider this an on-going conversation, until 2008 brings in more new releases...
