Current bands I am very fond of include
Bloc Party
The Kills (just ignore the Kate Moss gossip-column stuff - they are the best live act going at the moment)
The Raveonettes
The Dead Weather (Sort of crosses over with the Kills but Alison Mosshart rocks)
David R Black
Dragons
Maybe not-so-new but if you've been in hibernation - Sigur Ros, the White Stripes, the Raconteurs,
