Query: A Bad Experiment

Liars has done some good work. I know everyone has their own tastes. I thought their earlier work was a lot better. This is very painful to listen to. The songs are not at all pleasurable to listen to. Now here comes my controversial statement... It is by far one of the worst indie rock albums I have ever heard. It may very well be the worst in my mind. No offense to any Liars fans, but this is really bad. There's nothing wrong with experimental music or trying new things. Maybe this is just a bad experiment. Liars are talented musicians, I mean if Angus Andrew can get a girl like Karen O of the Yeah Yeah Yeahs, then he must be talented. But, this album is not up to par.
