This post on ACL reminded me about Take Away Shows. I'm not really sure about the origins of these or really anything about them except they are awesome, impromptu shows with some great bands.
Some of my favorites:
Okkervil River
Arcade Fire
Andrew Bird
Sufjan Stevens
David Bazan
Jose Gonzalez
Beirut (really awesome)
Castanets
Bon Iver
Fleet Foxes
Seriously, check 'em out. I'm sure you'll find something you like if you like good music.
