I have to confess that, although I'm a big fan of the 'Gramme, I've only heard clips of Arab Strap's latest LP.
Therefore, suggesting that they're similar is probably uninformed/a bit daft, but prima facie, it does sound that they're not a million miles away, sonically/lyrically speaking.
Am I onto something here?
Also, subquestion - is "The Last Romance" worth buying? My feeling is...probably yes.
