Tickets are $20 ($28.75 with fees)
From 9:30 Club announcement:
"Father John Misty the sassiest frontman in recent memory (with one of the best damn records of 2012) has sashayed sweatily through various sold out DC shows, and we are so ready for him to spread his wings - or rather swivel his hips - on our stage. These tix will certainly go very fast."
It's not listed on the 9:30 Club website yet (as of 2/21/13) but the link for tickets above takes you to the Ticketfly site.
