One of my favourite bands is Phoenix. They are French and produce perfect indie/alternative/pop music. They also happen to have great style, very typically French - lots of APC shirts, peacoats and well worn boots. I recommend you give their music a listen, I think it has a broad appeal. Their website has a great journal where they post pictures regularly: http://wearephoenix.com/journal/
I was also lucky enough to see them perform live last year in Birmingham. I had a great time and was pleased to discover they are just as good live! These pictures are my own.
