Two garage rock bands, one new, one not so new.
The Libertines are the well-known garage rock band from England that released albums in 2002 and 2004 and subsequently broke up. I only just started listening to them and have really started to like them.
A similar style of band is Calypso from Brooklyn. They only have an EP out, but it's really promising. Look for more good material from them soon.
The Libertines - Don't Look Back into the Sun
The Libertines - Time for Heroes
Calypso - Son of a Gun
Calypso - Casually Sad Mercedes
