Sara Bareilles

Likened to a well-adjusted Fiona Apple, piano-bashing Californian singer Bareilles hit big in 2007 with bouncy pop hit 'Love Song' and subsequently worked with the likes of Questlove and Pharrell. Her latest single 'Brave' smashed as well, although being featured in a Windows commercial certainly helped. She'll now be back in Japan for the first time since 2011, with this gig forming a part of her worldwide Little Black Dress Tour.
