Yay, electroswing! Couple of recommendations:
Parov Stelar’s the guy who started it all, and his songs are fantastic. Try ‘The Snake’ (http://www.youtube.com/watch?v=PKWE8duRsYw)
The Correspondents are wonderful, particularly live; try Fear and Delight (which has a fantastic video - http://www.youtube.com/watch?v=ABS-mlep5rY), Cheating with You, and the brilliant What Happened to Soho?
JFB does more dubstep-heavy electroswing; try Swing Bum: (http://www.youtube.com/watch?v=1BMyA6_oi28)
Lastly, I don’t know if Molotov Jukebox’s Don’t Panic ( http://www.youtube.com/watch?v=8bJqNR0nrUE) really counts as electroswing, but it’s got the right attitude. The singer is Natalia Tena, who plays Tonks in the Harry Potter movies and Osha in Game of Thrones…
