They announced this tantalizing piece of information in an update on their Twitter page today (December 9). As you may already know, One Chord to Another contains celebrated songs like "The Good in Everyone" and "Everything You've Done Wrong," and, well, is generally awesome.
Just to be clear, this show doesn't include a performance from Fucked Up, although it is presented by the acclaimed hardcore act. Rather, the December 21 bill is rounded out by the Rural Alberta Advantage, Ohbijou and Bonjay.
Fucked Up will perform the night before (December 20) at the same venue alongside the Sadies, PS I Love You and Quest for Fire. They will be playing David Comes to Life in full.
Tickets for each night are $20 a piece and are available from Fucked Up's webstore. Once you've got your ticket, that would be as good a time as any to listen to One Chord to Another and start re-memorizing those lyrics.
Of course, when you're at the show, don't forget to pick up Sloan and Fucked Up's split seven-inch.
