A dozen years is a long time to take a break, but last night on Jimmy Fallon (who is to reunited emo bands what Ed Sullivan was to rock in the '60s) Jawbox made their triumphant return, performing "Savory" from their excellent For Your Own Special Sweetheart recording. The re-released version of that album is available now, and according to the band this was their lone reunion performance. No new songs. No new tours. Just Jimmy Fallon.
