The style ranges from Jefferson Airplane and Kate Bush, a successful combination for my taste.
Florence + The Machine reached several peaks of musicality and surreal atmosphere, especially during the beaches 2 (Rabbit Heart) and 9 (Cosmic Love). The lowest range for my taste is the 5 (Kiss With A Fist), yet released as a single in England.
Only downside: I have purchased good the DVD edition had it been available :(
