The second group I listened to are called 'Metric' who I stumbled across on youtube. I found it hard to categorize this band, their music is a mix of indie, pop and something else I can't quite put my finger on, but even so, they are a good listen to on a slow day.
The third group are called 'Ladytron', many people commenting on the videos for 'School Of Seven bells' were recommending this group so I decided to give them a listen. I've only heard a few songs so far but they fail to disappoint.
One of the best songs I've heard in a long time is by 'The Cinematic Orchestra' which is called 'To Build A Home'. There's something about this song that gets my mind flowing with ideas and things I wouldn't usually think of, I found the song to be so amazing that I've even tried pimping it out to other people, but nobody seems to be that interested in it.
