Against Me!'s Tom Gabel

Tom Gabel's no stranger to video performances, what with his new series in support of his recently released solo album Heart Burns. But when SPIN.com caught up with the punk rock troubadour in Brooklyn to film a live acoustic performance recently, Gabel was treated to, well, a lesson in multiplicity.

Below, watch Gabel perform a duet with himself -- admittedly a first for the rocker -- on new tracks "Harsh Realms" and "Anna Is a Stool Pigeon" just hours before he lit up New York's Knitting Factory with old Against Me! obscurities.

Watch: Tom Gabel, "Harsh Realms"
