SCANDAL has grown as a band, it seems. I'm not sure if their new songs are still written mostly by third party composers(haven't checked their single's credits), but at least they're drifting themselves away from the schoolgirl image... into a more radical Gaga-esque fashion which I don't think is their own idea. Such is the bane of being a band for a Japanese recording company; your image will be decided by the management for the masses.
Their most recent live performance I can find, without the crazy kimono derivative. Their maturity and confidence has grown and it shows here. Actually they have new songs to go with this performance, but I don't like Harukaze so I picked this FMA theme instead.
