Florence And The Machine - Shake It Out...Live @ the Boom Boom Room. A small intimate setting with Kanye West, Emma Roberts & othe celebs in attendance. This is a perfect example of what an amazing talent she is. Shake it out is a great song that can get stuck in your head for days but like much of "Ceremonials", the great songs can get lost in overly grandiose production. Florence doesn't need any extra help to be epic.
