I just grabbed Florence and the Machine's debut album, Lungs, and I have to say, "I'm Hooked". The first track, Dog Days are Over opens with a strumming ukulele (I think) and then slowly picks up the pace to a thumping track that dares you not to dance before slowing back down to focus on Florence Welch's vocals. You don't get to relax long though before the pumping returns and you find your foot tapping to the rocky-bluesy force. If you don't like to dance you could easily drive in excess of the speed limit while buffeted by the forceful beat. [video]
Dog Days is followed by a totally different vibe in the song "Rabbit Heart" which is a light airy song laid on a solid bass backbeat that seems to focus far more on Florence's vocals. "The Machine" also seems to be far more present in this song and to good effect as they sound more like a background choir than just some accompanying singers. [video].
Each track on the album seems to stand on it's own and I can easily recommend you pick up the album as you won't be disappointed with any of the songs. I'm not entirely sure Florence and the Machine deserve the "Indie' moniker considering their album hit #2 in the UK - but from a US perspective they are pretty unheard of and I doubt they will get much airtime here so I'm giving them the technical nod to Indie Rock.
Florence is already working on the groups next album so hopefully by the time you have worn out your earbuds with "Lungs" (only 8 bucks at Amazon) you'll be ready to experience a bit more of Florence Welch and her band of haunting vocalists.
