A few bands that I've been hardcore on lately:
The Distortions: Like the mellower, dreamy side of Jesus and Mary Chain and Black Rebel Motorcycle Club.
The Violets: Angular, post punk with a female vocalist. Kind of like early Yeah, Yeah, Yeahs if they covered Siouxsie and the Banshees early stuff.
The Domino State: Melodic, moody post punk. Like Coldplay with a lot more balls or The Glam.
